Errors with GWT setup

[Eternat]

I am having trouble getting roo to set up GWT properly. I have a script that sets up a number of abstract and standard entities followed by a section that sets up all the fields for each entity followed by my mvc, logging, security, and gwt setup commands. The scripts executes without error however when I run mvn gwt:run I get a whole slew of errors that are of this form \client\managed\activity\<Entity>EditActivityWrapp er.java:[11,39] error: cannot find symbol

I am using
roo 1.2.0.M1
maven 3.0.3
java 1.7

note: I also changed the pom.xml file to say that I am using java 1.6 to workaround another compile error

I am using a lot of inheritance including double inheritance in some cases. I have read that gwt RequestFactory does not support this; is that true?
If anyone knows what is happening or even if anyone is having similar problems please let me know.

EDIT: I rewrote my script to not include any abstraction or inheritance and it works like a charm now.

Thanks
