Extending Valid Elements for Tiny MCE returns 404


Been trying to get this working since Friday following all the information in the many post available on the next but I just can't seem to get it working and don't really understand why.

I've tried following the instructions in here and no joy:


I added the TinyMceValidElements class and pasted the empty file handler underneath it within the same namespace.  I've updated the EpiServer.config by inserting

What am I doing wrong?  Followed the instructions verbatum and finding this all a bit frustrating now.  Everyone else claims it works but I'm not seeing how.

Any help/suggestions would be greatly appreciated.

Instead of using the empty file handler method, have you tried adding an empty file with the correct name (editor_plugin.js) in the file path it's requesting?

Clear all your temporary internet files and hard refresh the browser. TinyMCE is usually heavily cached.

You should be able to set the ServerSideOnly property on the attribute to plug-in false and thus removing the need to call the JavaScript file on the client.

Linus, I've tried ServerSideOnly. But it's still trying to access /util/Editor/tinymce/plugins/{my plugin name}/editor_plugin.js?moduleArea=Util.

We have empty files for every plugin, but it would be nice to be able skip that.

Hi Johan!

I cannot reproduce the issue. If I copy the plug in from Chris's blog post and just compile it and load the error, I get the 404, but after adding ServerSideOnly = true, the call is not made any more.
