This isn't a bug, this is just how the class is defined - DateBox is not a ValueBox, so attempting to pass it into a function that expects a ValueBox will naturally fail.
A few options you have: Try making a ValueBoxBase instance that wraps a DateBox - this may or may not be possible, but will be necessary if you want to use the stock ValueBoxEditorDecorator, which requires access to a ValueBoxEditor. The other, preferred option would be to make something like a DateBoxEditorDecorator. Since DateBox doesn't have any parsing or validating stuff, it doesnt generate its own errors (so doesnt need a delegate), so this will have some differences from the ValueBoxEditorDecorator. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
