WYSIWYG editors utilize custom JS that doesn't work when ajax loaded in. There's no fix for it until I can figure out how to make that JS load and work without fatal JS errors and have it work for any WYSIWYG editor you use. It's just not as easy as it sounds and a lot of fault is with how poorly the editor binds to its textarea field.

Ok, latest build has a workaround implemented for TinyMCE. CodeMirror it's not possible because of how the editor binds to the textarea input. JCE is untested, but if they use jQuery to bind the textarea editor it should have no issues rebinding. That's the best I can do for now as editors not using jQuery or safely reusable JS to bind simply won't rebind properly.

To explain why this worked in very very old releases it's because it used to render the edit HTML on initial view. It was never ajax loaded in. Now it's ajax loaded in so it's only rendered if it's necessary. The previous usage basically bloated the page 10x over with HTML and hurt performance significantly. That isn't an issue now with on-demand inline editing since it just loads via ajax. This isn't a problem with CB Core Fields Ajax, but a problem with how these WYSIWYG editors bind to their textarea inputs. I have to basically implement manual workarounds for each one to rebind, unfortunately.

Nope, not at this time. It may not be possible depending on how JCE binds to its editors. It however works perfectly fine with TinyMCE.
