Some errors (including the fatal one) come from the GXT version being too old and incompatible
with GWT 2.4 (there was a change in GWT 2.2, that broke binary compatibility, so 3rd-party
generators have to be compiled against GWT 2.2+)

You might also want to update your gwt-maven-plugin version.

The Enumeration / generics errors look highly suspicious. Please comment back if you
still experience them after updating GXT and gwt-maven-plugin.
