WYSIWYG unable to set default value in ui component

[milansimek]

Preconditions

1. Magento v2.1.6

Steps to reproduce

1. Create a form uicomponent
2. Create a wysiwyg editor field
3. Add a default value

Expected result

1. The default value should be used when no value is set. This works properly for other fields like textarea's etc.

Actual result

1. The default value is not used. Editor is empty

How to fix

Edit
magento2/app/code/Magento/Ui/view/base/web/js/form/element/wysiwyg.js

Change value in the defaults object to null. Currently it's ''

Hello! Thank you for submission.
When I was on step 3, I added

            $fieldset->addField(
                'content',
                'editor',
                [
                    'name' => 'content',
                    'label'     => 'WWG',
                    'title'     => 'WYSIWYG',
                    'style'     => 'height:15em',
                    'config'    => $this->_wysiwyg->getConfig(),
                    'wysiwyg'   => true,
                    'required'  => false,
                    'value'     => 'Unusualy default value!'
                ]
            );

This worked for me on Magento v2.2.0. Please provide more details.

Hi, thanks for your reply.

You should create a form ui component (XML), not a form PHP block.

@milansimek, I interested in reproducing this issue. It would save me some time on reproducing this issue if you could provide me the code for those 3 steps that you described. Please provide the code. Thank you in advance.

@TomashKhamlai Hi, sorry for my late reply. I missed your comment somehow.

You can use XML code such as the following to add a WYSIWYG editor to a form UI component:

 <field name="detail">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="dataType" xsi:type="string">text</item>
                    <item name="formElement" xsi:type="string">wysiwyg</item>
                    <item name="source" xsi:type="string">sample_shop</item>
                    <item name="label" xsi:type="string">Detail</item>

                    <item name="template" xsi:type="string">ui/form/field</item>
                    <item name="wysiwyg" xsi:type="boolean">true</item>
                    <item name="dataScope" xsi:type="string">detail</item>
                    <item name="sortOrder" xsi:type="number">50</item>
                    <item name="rows" xsi:type="number">8</item>
                     <item name="default" xsi:type="string">this is the default text</item>
                </item>
            </argument>
        </field>

The <item name="default" xsi:type="string">this is the default text</item> part doesn't work.

If you update app/code/Magento/Ui/view/base/web/js/form/element/wysiwyg.js like I mentioned in my first post, it will work properly.
