Did you, by any chance, originally deploy the portlet with only view mode, and then later add edit mode? If you did that, then the portal is not updating the allowed types for the portlet. You might have to undeploy the portlet, then go into the Management Portlet and make sure that all traces of the portlet and its instances are gone, and then deploy the portlet again.
