Sat Jun 6 20:34:19 EDT 2009

Hello folks,

I have created a JIRA for this at
https://jira.jboss.org/jira/browse/GUVNOR-356
I have attached a simple usecase and all relevant artifacts.

Created a new repository ( deleted repository folder and repository.xml)
created new category - Ads
created new package - Ads
Uploaded model
Created new technical rule ---> at this point, both my objects Contact and
Contact1 show up.
Created simple rule with just the Contact object.
Built package and deployed snapshot.
Invoked using ruby code, sending in a Contact object using json.
Attached .pkg file shows that it recognizes the Contact1 object.
