[rules-users] KnowledgeAgent Issue

[Esteban Aliverti]

Someone mentioned me the problem some time ago. I have a fix for it in my
local repo, butI was waiting for the trunk to be stable to test it.
The problem is that under certain circumstances, the kagent is reusing the
same kbuilder to compile all the resources present in a change-set (the
modifications I have force the agent to use a new kbuilder for each
resource).
The only difference between what you are reporting and the problem I'm
talking about is that in my case all the rules, functions, etc were added to
the kbase, but all within the same package. No matter the real package
definition. Is this your case also?

Please file a bug report and let me know.

Best Regards,
