Hi, you could consider it a warning. Designer when validating checks Guvnor to see if there is a process image already available for your process. If there is not, it raises that warning. In the Designer you can generate the process image by clicking on the PNG button on the footer bar. Once you have generated your process image and re-validate this warning should no longer be there.

Re: [rules-users] Problem importing bpmn process into oryx designer
The conditional expression attributes are actually part of the sequence flows that are coming out of the gateway, and not the gatewat itself. Click on the sequence flows and you will be able to set the logic there. The Eclipse plugin does this somewhat different in that the conditional expressions are part of the gateway itself...just notice this small difference between the editors. Thanks.

Re: [rules-users] Knowledge Base and Multiple Sessions
I would say no. I think that every session has its own RETE nodes filled with its own facts. May be the different RETE instances share some evaluators (or at least generated dynamic classes that represent nodes) so it could use a bit less memory than recreating the same kbase again and again (which can affect PermGenSpace on some jvm where GC is not good at purging the permgen). But the real perf hit should be due to using multiple Thread in a single jvm : if you add too much threads, gc, swap and so on can become long.

Re: [rules-users] Multiple DRL for one Package
I think that RETE is stored in kbase, and kPackage contains only some kind of AST for rules. So adding some rules (of same package or not) in a kbase (or a kbuilder) don't use the origin .. And mroe than that, I am pretty sure that rules are shared in RETE even if they are from different packages (this way the RETE can share more patterns and improve propagation). But I am not a DEV guy, so all of the previous is only my own conclusions. When you do that, using your kbuilder, does the kbuilder return 1 or 2 knowledgePackage ? And anyway, why does it matters ?

Re: [rules-users] Knowledge Base and Multiple Sessions
I did run the test and your assessment is accurate. Sessions using different knowledge bases to not perform any better. For the most part each thread is running a separate rule box, however there is one set of rules which all messages must go through (millions) while the others will have a very small subset sent to them based on what the first set determined...
