[rules-users] Guvnor Issues

Hi, I've been working with the Model feature in Guvnor 5.M4 and have some questions: 1. Is there a way to delete a fact type once created? 2. When I declare a field as a Date it gets included as a java.lang.Date and the fact will not validate. 3. If I have created two facts, the one created first cannot reference the second one as the type of a field. The second on can reference the first. It would be nice to support this forward -referencing feature. I'd be happy to enter any of these in Jira if they are not already present (couldn't find them). Thanks, Herm
