What is it you want to do within a <process-action> element? If you told
me that I think I could answer your questions better.
The reason you'd want to use the <process-action> element is if you wanted
to interact with the process while it is running. To do that you can use
the STAXProcessHandle variable to obtain the process' handle (if the
process was not started using the 'shell' mode). Note that the STAX
User's Guide contains an example of how to use the <process-action> to
send a message via the QUEUE service to the process (just an example of
one thing you can do to interact with a process via a <process-action>).
Note that if you simply want to know when a process completes, you'll know
this after the <process> element completes and you don't need a
<process-action> element.
If a block is terminated and the block contains one or more <process>
elements, then STAX will attempt to stop the process(es) before
terminating the block (but if a process cannot be terminated, it
terminates the block anyway).
I think if you simply try using the <process-action> element, you'll
better understand how it works (if you really have a need to use it).

[staf-users] How to stop "process-action"
Hi,
I would like to have a Jython-<script> running in parallel to a process
using <process-action>.
STAX User Guide tells me 'If the process completes before the task
completes, the process
will remain in a non-complete state until the task completes.'
So, how can the script observe the process to make sure that it exits
after the process has
exited?
And what will happen if the process is killed by a block termination from
STAXMon? AFAICS,
STAX waits for the process to exit after sending the signal. Does it also
wait for termination
of <process-action>?
Best regards
Bodo
