Unable to process the case: Attribute not found in the scope chain
Hi, I'm working on a project with two different processes that communicate through messages. Up to yesterday, everything worked fine using collaboration in both selective and not selective way. Without modifying the related logic, now at a certain point of execution the messages are not sent anymore and the following error messages is thrown: "Unable to process the case: Attribute not found in the scope chain". Since I use an automatic way of assign the caseId of the process to which send the message (through xPath), I tried also to write the caseId at runtime (matching of course the process that is waiting) but it does not work as well.
I hope that you could help me, thanks for your attention.
