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
