Michael, Thanks a ton for your replies. So it's not just us..., you describe exactly the experience we've been having with the Editor Widget in ExtJS. We've been banging our heads against our desk for a week trying to troubleshoot this one (what should have been a 30 minute coding exercise).
In FF, examing the HTML 'editorDiv' element with FireBug, I can definitely see that the <div> for the "drawingToolbar" is getting hosed. It is missing the dijitToolbarFocused and dijitFocused classes, and no additional HTML is generated inside this div. Very frustrating.
Maybe we will need to abandon extjs too. If we somehow figure it out, I'll be sure to report back to you. Thanks also for sharing the code you've been developing.
Jason
