Hi,

I am trying to use RCP to develop a BRMS. But I am a newcomer of both RCP and DRools. The problem in my program is:

A view can not be displayed properly while the DRools program is added in my RCP project. But if I disable below statement, the view can be displayed:

workingMemory = ruleBase.newStatefulSession();

Error message and a view RCP codes in which rule is fired are attached.

My steps of constructing the RCP+DRools project:

1. Create Plug-in project with RCP

2. Add customized view and add some buttons

3. Run as Eclipse Application, everything is fine

4. "Convert to DRools project" using the pop-up menu, some DRools libraries were added.

5. Add button event and fire rules in a view - "EditView"

6. Run as Eclipse Application, EditView can not be displayed properly and throw out error message.

7. if "workingMemory = ruleBase.newStatefulSession();" is disabled, the view can be display correctly again.

Is my DRools calling method in RCP correct?

Please comment.

Thanks,

David
