Hello.
I've just developed two simple plugins based on the new "Widgets" tutorial for adding HTML5 <audio> and <video> elements to my editor.
By default, CKEditor was stripping out all of the <audio>, <video>, and <source> tags, so I added requiredContent and allowedContent properties to the widget definitions.
After doing so, I can properly load existing markup into a CKEditor instance without stripping out these tags, and the editor properly wraps the audio and video players in a widget placeholder so I can edit them by double-clicking. The toolbar buttons for both my plugins, however, are disabled, so I cannot create new ones.
Is there something I need to do to the global CKEditor configuration, the widget configuration, or both to re-enable these buttons? I imagine it's related to allowedContent somehow, but no amount of experimentation has restored the functionality of these toolbar buttons.
Thanks.
