Root Cause

When a modal is closed through PopModalAsync, the framework cascades SendNavigatedTo(Pop) down to the current child of the TabbedPage (for example, Tab1). Inside SendNavigatedTo, a guard (if (HasNavigatedTo) return) prevents duplicate OnNavigatedTo events from firing. This guard was introduced in PR #31931 to fix issue #23902 .

The issue occurs when the user switches tabs while a modal is open. That tab switch triggers a normal Replace navigation within the TabbedPage, which sets Tab1.HasNavigatedTo = true. Later, when the modal is closed, SendNavigatedFrom is invoked only on the modal page itself — the tab child pages never receive SendNavigatedFrom, so their HasNavigatedTo flags are not reset.

As a result, when the subsequent Pop cascade reaches Tab1, its HasNavigatedTo flag is still true from the earlier in-modal tab switch. The duplicate-event guard therefore incorrectly suppresses the OnNavigatedTo event that should fire when returning to the page after the modal closes.

Description of Change

Updated Page.SendNavigatedTo so that when navigation cascades into a container child page, the child’s HasNavigatedTo flag is reset before cascading — but only for NavigationType.Pop.

Pop represents returning to an existing page and should always trigger a legitimate new OnNavigatedTo event. Push and Replace flows remain unchanged, preserving the original duplicate-event protection introduced for issue #23902.

Pre-Flight — Context & Validation

Issue: #35756 - Changing TabbedPage.CurrentPage from modal page no longer fires OnNavigatedTo on PopModalAsync
PR: #35803 - Fix OnNavigatedTo not firing after PopModalAsync when tab is changed inside modal
Platforms Affected: iOS, Android reported; PR labeled iOS/Android/Windows/macOS; iOS used for gate and candidate testing
Files Changed: 1 implementation, 2 test

Key Findings

• Issue #35756 is a regression from 10.0.60 to 10.0.70: after changing TabbedPage.CurrentPage from inside a modal, PopModalAsync should fire OnNavigatedTo again for the returned-to tab, producing count 3 instead of count 2.
• PR #35803 changes Page.SendNavigatedTo so a container's current child page can receive a Pop navigated-to event even if a prior tab switch inside a modal left the child's HasNavigatedTo flag set.
• Gate already passed on iOS: the new Issue35756 UI test fails without the fix and passes with the fix.
• PR discussion through authenticated gh could not be fetched, but public API metadata, local diff, and generated gate artifacts were available.

Code Review Summary

Verdict: LGTM
Confidence: high
Errors: 0 | Warnings: 0 | Suggestions: 2

Key code review findings:

• Suggestion: src/Controls/src/Core/Page/Page.cs:856 comment about why PopToRoot is excluded is slightly imprecise, but behavior is correct.
• Suggestion: src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue35756.cs could optionally add a no-tab-switch regression assertion to prove the original duplicate-navigation guard remains intact.

Code Review — Deep Analysis

Code Review — PR #35803

Independent Assessment

What this changes: Page.SendNavigatedTo now explicitly resets a container child page's HasNavigatedTo flag to false before cascading a Pop navigation event into it. The cascade logic is otherwise identical to the pre-existing code.

Inferred motivation: The HasNavigatedTo guard that prevents duplicate OnNavigatedTo events can be spuriously set to true on a tab-child page before the modal closes, because a tab switch from inside a modal fires SendNavigatedTo(Replace) directly on the child — bypassing the SendNavigatedFrom call that would have cleared the flag. When the modal is later dismissed, the guard silently swallows the OnNavigatedTo for the returning page.

---

Reconciliation with PR Narrative

Author claims: The regression was introduced by PR #31931 (fix for #23902). That PR added the HasNavigatedTo guard to prevent duplicate OnNavigatedTo. The tab-switch-inside-modal scenario exposes a gap: SendNavigatedFrom is only called on the modal, not on the TabbedPage's children, so their HasNavigatedTo is never reset before the Pop cascade.

Agreement: The analysis precisely matches the code. The fix is narrowly scoped and does not weaken the original guard introduced for #23902.

Findings

💡 Suggestion — Comment about PopToRoot exclusion is slightly imprecise

Page.cs:856

// PopToRoot is excluded: SendNavigatedFrom already resets all flags before PopToRoot cascades.

This reasoning is partially inaccurate. For PopToRoot within a NavigationPage, SendNavigatedFrom is only called on the top-of-stack page (previousPage), not on the root TabbedPage's children directly. The reason PopToRoot doesn't need the reset is different: when you push away from a TabbedPage to start building a nav stack, SendNavigatedFrom(Push) cascades through the TabbedPage to its CurrentPage, resetting HasNavigatedTo at that point. By the time PopToRoot fires, the child flag is already false — not because PopToRoot's own SendNavigatedFrom resets it, but because the earlier Push already did. The comment could mislead future readers.

Not a correctness bug — the behavior is correct. Just a comment to revisit.

💡 Suggestion — Test missing a "no regression" assertion for the non-tab-switch flow

TestCases.Shared.Tests/Tests/Issues/Issue35756.cs

The test verifies the fix scenario (count=3 after pop). It doesn't assert that OnNavigatedTo doesn't over-fire in a normal pop (no tab switch). A count of 3 is the right number here, but a second test method could validate that popping a modal without switching tabs still yields count=2 (initial + pop), confirming the original HasNavigatedTo guard still holds. This is optional — UI test bloat is a real concern — but it would prevent a future regression that removes the guard entirely.

---

Devil's Advocate

"Is the Pop reset too broad?" — Considered: this also fires for NavigationPage.CurrentPage when a modal is popped over a NavigationPage. But NavigationPage.CurrentPage.HasNavigatedTo is false at that point (it was reset by SendNavigatedFrom(Push) when the modal was pushed), so the explicit reset is a no-op.

"Could the tab-switch Navigate Replace fire a count increment unexpectedly?" — The test expects count=3: initial(1), Replace from tab-switch-inside-modal(2), Pop from dismiss(3). This is intentional and correct — the Replace fires SendNavigatedTo directly on Tab1 from MultiPage.cs:107, which is the designed behavior for page switching. The fix ensures the Pop also fires, which is the bug being fixed.

"Is Shell affected?" — Shell implements IPageContainer<Page>, so the cascade applies to it too. When a modal is popped over Shell, the SendNavigatedFrom(Push) cascade at modal-push time already clears Shell.CurrentPage.HasNavigatedTo, making the new reset a no-op. No regression risk.

"Could count be 4 if something fires twice?" — The HasNavigatedTo guard on this (TabbedPage) prevents TabbedPage from re-firing. The child's guard is reset then immediately set again via containerChild.SendNavigatedTo, and that call respects the guard for any of the child's own children. No double-fire path.

---

Verdict: LGTM

Confidence: high

Summary: The fix is a minimal, correctly-scoped change that addresses the exact gap in the HasNavigatedTo guard. The HostApp reproducer and UI test accurately cover the bug scenario with the right expected value. The two suggestions above are optional polish items, not blockers.

Fix — Analysis & Comparison

Fix Candidates

#	Source	Approach	Test Result	Files Changed	Notes
1	try-fix	Let NavigationType.Pop bypass the HasNavigatedTo duplicate-event guard in Page.SendNavigatedTo.	✅ PASS	1 file	Passed Issue35756, but broader than PR because it changes all Pop guard semantics and risks reintroducing duplicate Pop notifications fixed by #23902.
2	try-fix	Clear selected child navigation state from MultiPage.CurrentPage when the container itself is inactive under a modal.	✅ PASS	2 files	Passed Issue35756, but more invasive than PR because it adds an internal helper and changes MultiPage replacement semantics globally.
PR	PR #35803	Reset only the cascaded container child before NavigationType.Pop in Page.SendNavigatedTo.	✅ PASSED (Gate)	1 file	Narrowest passing fix; preserves Replace semantics and original duplicate guard behavior outside the stale child Pop cascade.

Cross-Pollination

Model	Round	New Ideas?	Details
maui-expert-reviewer	2	No	Considered a prevention approach that would skip MultiPage.CurrentPage Replace SendNavigatedTo while the container is inactive. Rejected as not worth testing because it changes observable Replace behavior for tabs while a modal is open and is therefore broader than the PR.

Exhausted: Yes
Selected Fix: PR's fix — It is the narrowest validated solution: it acts only where stale state causes harm, only for NavigationType.Pop, only for the current child cascade, and does not alter normal Replace or all-Pop event semantics.

Attempt Details

try-fix-1 — Pop bypasses guard

• Approach: Change if (HasNavigatedTo) to if (HasNavigatedTo && args.NavigationType != NavigationType.Pop) in Page.SendNavigatedTo.
• Diff: CustomAgentLogsTmp/PRState/35803/PRAgent/try-fix/attempt-1/fix.diff
• Test result: ✅ PASS, BuildAndRunHostApp.ps1 -Platform ios -TestFilter "Issue35756"
• Failure analysis: Not failed, but rejected because it weakens duplicate-event protection for every Pop path rather than only the stale child cascade.

try-fix-2 — Clear inactive MultiPage child state

• Approach: Add Page.ClearHasNavigatedTo() and call it after MultiPage.CurrentPage sends Replace NavigatedTo when the MultiPage itself is not navigated-to.
• Diff: CustomAgentLogsTmp/PRState/35803/PRAgent/try-fix/attempt-2/fix.diff
• Test result: ✅ PASS, BuildAndRunHostApp.ps1 -Platform ios -TestFilter "Issue35756"
• Failure analysis: Not failed, but rejected because it expands the changed surface to MultiPage plus an internal helper and changes inactive tab replacement state globally.

Report — Final Recommendation

Comparative Report — PR #35803

Candidate Ranking

Rank	Candidate	Regression result	Assessment
1	pr	✅ Passed iOS gate	Narrowest validated fix. It clears only the stale current-child HasNavigatedTo state immediately before a container cascades NavigationType.Pop, preserving the duplicate-event guard and normal tab replacement semantics elsewhere.
1	pr-plus-reviewer	✅ Same as pr	Expert reviewer returned no actionable findings, so this candidate is behaviorally identical to pr; it ties with pr but does not improve on it.
3	try-fix-2	✅ Passed targeted iOS test	Fixes the stale state earlier by clearing selected child state after inactive MultiPage.CurrentPage replacement. This is broader than the PR because it adds a helper and changes inactive MultiPage replacement state globally.
4	try-fix-1	✅ Passed targeted iOS test	Allows every NavigationType.Pop to bypass the duplicate HasNavigatedTo guard. This is the broadest passing approach and risks reintroducing duplicate Pop notifications that the guard was intended to prevent.

No candidate failed regression tests, so ranking is based on correctness risk and scope.

Candidate Details

pr

The submitted PR resets the current child page's HasNavigatedTo flag only when a container is cascading a NavigationType.Pop. This directly addresses the stale flag created when a tab is selected while a modal is open, allowing the pop-return notification to reach the selected tab. It leaves Replace, Push, and ordinary duplicate OnNavigatedTo suppression unchanged.

pr-plus-reviewer

The MAUI expert reviewer found no actionable inline findings, and the raw findings artifact is an empty array. Because no feedback needed to be applied, this candidate is the same implementation as pr.

try-fix-2

This candidate clears selected child navigation state from MultiPage.CurrentPage when the MultiPage itself is inactive. It passed the targeted iOS regression, but it changes a broader lifecycle point and introduces new internal API surface solely to manage the state transition.

try-fix-1

This candidate bypasses the HasNavigatedTo duplicate guard for all Pop navigation. It passed the targeted iOS regression, but it changes the meaning of Pop delivery globally rather than only repairing the stale child cascade that causes this issue.

Winner

pr is the winning candidate. pr-plus-reviewer is equivalent because the expert reviewer had no changes to apply, but the canonical submitted PR candidate is preferred for the manifest because it is the unchanged PR fix. It has the best risk profile among all passing candidates: targeted, minimal, and backed by the gate result showing the regression fails without the fix and passes with it.

Test Failure Review: Likely unrelated - click to expand

Overall verdict: Likely unrelated

All observed failures are in CarouselView, CollectionView, and visual snapshot tests — none of which are touched by this PR. The device-test pipeline has also been failing on main for at least five consecutive builds before this PR was evaluated.

Failure	Verdict	Evidence
maui-pr-devicetests — Android Helix (Mono) + Windows Helix	Likely unrelated	main branch failed this pipeline in all 5 recent builds (builds 1459940, 1455022, 1454817, 1451776, 1448204; spanning 06/03–06/11). Pre-existing baseline failure unrelated to this PR. Helix aggregate data returned 404 so individual work-item details could not be verified.
maui-pr-uitests — Android CollectionView (API 30)	Likely unrelated	Failures in VerifyHeaderTemplate*, VerifyHeaderView*, CollectionViewInfiniteScroll, VerifyDefaultScrollToRequested — all System.TimeoutException on element lookup. PR only modifies Page.cs TabbedPage navigation logic; no CollectionView code changed.
maui-pr-uitests — Android CarouselView CoreClr (API 30)	Likely unrelated	Ten VerifyCarouselView* tests time out waiting for elements. CarouselViewGoToPreviousCurrentItem fails with an ADB infrastructure error (broken pipe, exit code 224). PR does not touch CarouselView.
maui-pr-uitests — macOS UITests Controls Image/IndicatorView/IsEnabled/IsVisible	Likely unrelated	Issue16918Test fails with VisualTestFailedException. PR does not add or modify any visual snapshots. Platform mismatch (macOS-only visual test; PR is a TabbedPage navigation fix).
Build Analysis	Likely unrelated	Aggregated failure derived from the unrelated check failures above.

Recommended action

No action needed for these failures: device tests are a pre-existing baseline failure on main, and UI test failures are in unrelated areas (CarouselView, CollectionView, visual snapshots). The PR change in Page.cs and the Issue35756 test files are in the TabbedPage navigation area and are not implicated by any observed failure.

Evidence details

PR scope: 3 files changed — src/Controls/src/Core/Page/Page.cs, src/Controls/tests/TestCases.HostApp/Issues/Issue35756.cs, src/Controls/tests/TestCases.Shared.Tests/Tests/Issues/Issue35756.cs. Area: area-controls-tabbedpage.

Device tests baseline: maui-pr-devicetests builds on main that all resulted in failure: 1459940 (06/11), 1455022 (06/08), 1454817 (06/08), 1451776 (06/08), 1448204 (06/03). Helix work-item detail for PR build 1459867 returned HTTP 404.

CarouselView ADB error (infrastructure): OpenQA.Selenium.UnknownErrorException: Error executing adbExec ... 'Command ... adb -P 5037 -s emulator-5554 shell cmd package resolve-activity' exited with code 224; Command output: cmd: Failure calling service package: Broken pipe (32).

Visual test failure: VisualTestUtils.VisualTestFailedException on Issue16918Test (macOS); no snapshot files changed in this PR.

Limitation: No AzDO token was available; authenticated _apis/test APIs were skipped. Build metadata, timelines, and public logs were queried. maui-pr-uitests build 1459866 was still inProgress when context was gathered; additional jobs may complete with further results.
