One last update:
I don't think its a good idea to GWT.create() the ginjector multiple
times. I got rid of this by creating it once in a static field in my
entry point class, and then accessing that field within my generated
class. This brings me to another question:
To find the name of the entry point class, I had to create a
configuration property. Is there a way, within a generator, to access
the entry point class defined in the module:
<entry-point class='com.puzzlebazar.client.Puzzlebazar' />
