On a given exception the parallel bypass for the given process did not work

Dhiraj Kumar over 7 years ago

We have a parent process model that called a sub-process )( calling a web-service ) . The sub process failed while mapping the CDTs in the process model and we got the foloowing exception
ERROR:An error occurred while evaluating expression: individualQualifileResponse_cdt:ac!outMap[1].spvv (Invalid index: Cannot index bean property 'spvv') (Data Outputs)

This was the first problem .
The other problem was that the Exceptions path for this was not picked up . The exception path was configured on the sub-process based on a timer ( 1 minute ) .The script task configured on this is not getting invoked after the elapse time

Dhiraj,
For the 1st issue, try mapping the process variables instead of activity class parameters.
I don't think you can map activity class paramters as input or output for a subprocess node.
For the 2nd issue, unless the sub process node is started,the exception timer would not be activated.
As of now in the issue shown, sub process node is stuck with an error before even getting started.

Have a look here: forum.appian.com/.../Exception_Flows.html - "Error events are not currently supported as exception flow triggers."

I think a failed node will NOT trigger ANY exceptions. A solution could be to have a timer in parallel to the sub process to catch possible errors inside.

We had a similar issue where we kept a timer in front of the Node and retriggered if the status is not met for the timer, and once it is not triggering for more than 2 times or so, we made the flow go through exception path.

Exception path in the sense in an other alternate way.... not from the exception path of the failed node...
