Comment 3 Petr Nejedly 2005-11-23 12:59:56 UTC 
This used to work. Some recent change in editor have to cause this.
Collab keeps a JEditorPane and calls setContentType on it from time to time,
which should be legal, I think.

In this particular case, there is JEditorPane set to edit mime "text" (bound to
simple swing's DefaultEditorKit subclass), and then the mime is switched to
"text/html" (bound to editor's kit).
Comment 4 Miloslav Metelka 2005-11-24 12:41:28 UTC 
The change that caused this was issue 61103 but it's desirable as it prevents
repainting problems in the editor. I'll fix it in the view hierarchy.
