Jan Haderka commented on MAGNOLIA-1142:
---------------------------------------
as of 3.6.1:
- if participant can't be found or fails during execution, the error is logged
{code}
INFO openwfe.org.embed.impl.engine.AbstractEmbeddedParticipant
MgnlParticipant.java(consume:111) 07.08.2008 09:45:39 consume command
command-logWorkItem...
ERROR openwfe.org.embed.impl.engine.AbstractEmbeddedParticipant
MgnlParticipant.java(consume:135) 07.08.2008 09:45:39 No command has been
found through the magnolia catalog for name: command-logWorkItem
INFO openwfe.org.embed.impl.engine.AbstractEmbeddedParticipant
MgnlParticipant.java(consume:138) 07.08.2008 09:45:39 consume command
command-logWorkItem end
{code}
- there is not ATTRIBUTE_EXCEPTION nor is there any CommandNotFoundException
- actually correct behaviour in this case seems to indeed leave item stalled
since this is what OpenWFE does normally when failing to execute participant.
See [1] for details. The else-ref or default timeout in the workflow can take
care of resuming execution should one of the participants fail. Alternativally
such stalled workflow can be resumed or removed manually.

>
> i created a workflow with a command participant:
> <participant ref="command-logWorkItem"/>
> logWorkItem doesn't exist in any catalog of commands. And it doesn't exist
> in the catalog named 'default'. Stepping through the code in
> MgnlParticipant, I am not sure it does the right thing in that case.
> Specifically no reply to the engine is done. I think this would leave the
> item 'stalled'. Probably a failure to find the command should result in the
> item being rejected.
