Hi,

I won't answer your question, but I try to provide solution 🙂


A multi-instance activity ends when all instances are finished. However, it is possible to specify an expression that is evaluated every time one instance ends. When this expression evaluates to true, all remaining instances are destroyed and the multi-instance activity ends, continuing the process. Such an expression must be defined in the completionCondition child element.

Thanks, I missed the completion condition and was looking into other side using events.
