I found the solution. I was using an editor decorator to wrap the
number validating editor. In this case it appears that you must forward
the setDelegate from the editor decorator to its sub-editor as in:
@Override
public void setDelegate(EditorDelegate<T> delegate) {
if (editor instanceof HasEditorDelegate) {
((HasEditorDelegate<T>) editor).setDelegate(delegate);
}
}
It works now.
