Hello,
I am having similar problem but the case is different. I am using cute editor in jquery overlay popup. The popup will open when user hit either Add or Edit buttons.
1. In case of Add I am setting cute editor value with setHTML(" ") , at first attempt this will raise an error as "Uncaught TypeError: Object #<HTMLTableElement> has no method 'SetHTML'".
2. In case of edit I am setting values from db, but getting the same error as point 1. Interesting thing is that when I will open javascript console (tools - javascript console) in chrome suddenly I see that the text is appeared in the editor (wired).
Please reply ASAP.
