Process instance getting stuck at parallel gateway

[shuchi]

Hi,

I have a process definition which has a parallel gateway which leads to three user tasks. When my process instance reaches this parallel gateway, the three user tasks are not getting generated (I tried invoking runtime/tasks from the REST API) and the process instance is getting stuck at the parallel gateway itself.

What could be possibly wrong with the process diagram? Can anyone help?

Thanks,
Shuchi

After playing around with the process diagram I discovered that there were two flows which were leading to the same parallel gateway. Apparently, there should be just one incoming flow for a parallel gateway. Don't know why that is though.

No, it can have any number. The parallel gw waits until x executions have reached it, where x is the number of incoming sequence flow.
