Hi all, Is there any other solution if not using MVP, just a plain project with UiBinder widgets? e.g. main app has user data, determined at runtime; some widgets should be able to read and write to this.
I looked at http://code.google.com/webtoolkit/doc/latest/DevGuideUiBinder.html#Share_resource_instances but it seems this is just static data. Also looked at http://blog.jeffdouglas.com/2010/02/24/gwt-uibinder-passing-objects-to-widgets/ but it doesn't seem possible to write back to main app data.
