Exception during creation of RichTextToolbar

[Chris]

Before getting GWT designer (right now I'm testing out the evaluation copy and am determining whether I want to buy it), I created a simple app that used the code from the KitchenSink example project that came with GWT, to recreate the RichTextArea and RichTextToolbar as seen here:

http://gwt.google.com/samples/KitchenSi ... .html#Text

This application ran fine in Hosted mode before I got GWT Designer (and still does), but now when I try to look at it in the Design tab, in place of the RichTextToolbar, I get a pink colored box with text in it that says:
Exception during creation of:
RichTextToolbar
See "Error Log" for details.

Does anyone know what the problem could be?

Does anyone know what the problem could be?

Yes. RichTextToolbar is not a JavaBean compliant widget (it is missing a default constructor) and can't be used with GWT Designer without some modifications.

See the GWT Designer FAQ for custom widget requirements.
