nope, I think I am wrong, the condition expression from my previous post (ProcessVariable)
which is based on Salaboy sample does not allow me to get "request" from certain
process instance. It just allows to make an inference over all requests inserted in a
session.
So I still can not get how to get instanceid for the current process instance in condition
expression.

have you tried with such approach to the rule:
$processInstance : WorkflowProcessInstance()
$request : Request() from $processInstance.getVariable("request")
not exists(Issue(requestId == $request.id)
have not run that rule so it could have some minor issues but it should give you what you
looking for I think (if I understood the need right)

Hello, Maciej !
It says: Unable to resolve ObjectType 'exists' if I try to build a package which
includes a process with the expression you suggested:
$processInstance : org.drools.runtime.process.WorkflowProcessInstance()
$request : Request($id:id) from $processInstance.getVariable("request")
not exists(Issue(requestid == $id))
My first question is what is wrong with "exists"?
Secondly, are you sure that "$processInstance :
org.drools.runtime.process.WorkflowProcessInstance()" would give me just one fact
which represents current instance in case there are many instances are inserted in a
session as facts?
I really appreciate your efforts, thank you
Regards,
Dmitry Erkin

forgot to answer the other question - the rule will be executed for each process instance
that is available in working memory that satisfy rule condition. So once you process a
given process instance you could either retract the process instance from session or make
sure that for it condition will not be meet any more, for example insert Issue instance
with the id of request.

https://community.jboss.org/people/swiderski.maciej *Maciej*,
In my case
$processInstance : WorkflowProcessInstance()
$request : Request($id:id) from $processInstance.getVariable("request")
not (exists (Issue(requestId == $id)))
is not a rule but the flow condition in a jbpm process.
So does that condition return "true" for the process instance "A"
(requestId==1) if there are not any issues like Issue(requestId==1) in the session but
there is another process instance "B" (requestId==2) *in the same session* and
there are some issues like Issue(requestId==2) in the session as well?

Dmitry Erkin
