Can't reproduce with IE 8.0.6001.18702. Perhaps something else is going on there.

I tried to debug this error in IE8 (Developer tools, F12) and script stops with error on following code:


My IE8 is 8.0.6001.18999.

I am not sure where else should be problem?

I had to turn off debug mode to reproduce.

I don't have TinyMCE source, and patch diff highlighting isn't very helpful, so here's the sanity check I added to wp-includes/js/tinymce/plugins/media/editor_plugin.js

I changed




Note that wp-includes/js/tinymce/wp-tinymce.js.gz will also have to be rebuilt, as it contains the script above.

Some list table javascript is messing with TinyMCE. koopersmith is working on a fix.

Currently, the list table JavaScript resets all forms whenever a page is loaded. This is heavyhanded code.

In this case, it caused TinyMCE to break in IE8 while it was in the process of loading.

However, a reset of some sort is necessary. Without a reset, if you change various inputs on the page (i.e. search and filters) and refresh, the results will be reverted to the default, but the inputs will not. The solution I used was to selectively reset form values—only those found within the tablenav, search-box, and wp-list-table classes.

  • Resolution set to fixed
  • Status changed from assigned to closed

(In [17239]) Selectively reset list-table forms rather than all forms to avoid stompage. Props koopersmith. fixes #16098
