Cannot read property 'apply' of null

[daN4cat]

After upgrading from 1.10.0 to 1.11.0 the following code causes an error:

  // set data-selected on options that are programmatically selected
  // prior to initialization of bootstrap-select
  var _val = $.fn.val;
  $.fn.val = function(value){
    if (this.is('select') && value) {
      this.find('option[value="' + value + '"]').data('selected', true);
    }

    return _val.apply(this, arguments);
  };

the exception is thrown on the return line. It looks like _val is null.

What changed from 1.10.0 to 1.11.0 that could cause this error?

Can you provide an example? I can't recreate this.

We had that problem in this open source: jekkos/opensourcepos@9a6bd6e and I reverted the version to 1.10 to avoid issues.
As soon as I updated your plugin to 1.11 I got bug reports, see https://github.com/jekkos/opensourcepos/issues/813 and https://github.com/jekkos/opensourcepos/issues/812

Unfortunately I don't have the time to create a specific example, but OSPOS source is quite mature and ready to be delivered. It worked well for many months of development with your version 1.10.

@caseyjhol I was having the same problem and we rolled back to v1.10.0 and everything worked fine. Here is a link to a codeply that causes the problem.

To see the problem please do the following:

1. Click on Magnifying class
2. Type in J in the text box that just displayed (In the console, you will see the error)

If you roll back to an older version of bootstrap-select you will see the autocomplete run correctly.

I hope this helps, if not let me know and I'll try and update with some more.

Great - thanks, Ken. Will look into this.

Yes, we get the same issue with an autocomplete box.
