You're facing this issue:
http://code.google.com/p/google-web-toolkit/issues/detail?id=3973
This is because FormPanel.wrap(Element) doesn't create an iframe:
http://code.google.com/p/google-web-toolkit/source/browse/releases/1.7/user/src/com/google/gwt/user/client/ui/FormPanel.java#361
If you really do not want to submit within an iframe, then the
workaround is to use FormPanel.wrap(elt, true) to create the iframe,
so that the events are sinked, and then reset the form's target
(eventually using "_self" to target the "same window")
