Hello, I have a problem and I will appreciate any suggestion about it. This is my scenario:

I have several services orchestrated from jbpm, the starter service receive an xml through http, the xml is transformed (smooks) into an ArrayList<User>, the message is mapped to jbpm variable from esb as BODY_CONTENT.




My problems start when the process try to pause (I have a timer on it), I think it is because this kind of var is not persistable, this is the exeption

Can anyone propose a possible solution or point me to some direction for achieving this, please.

As a work around as I have tried to transform back the Collection into an xml string, so the process doesn't complain when paused. I would like to know how can I use that object model to generate an xml string using Smooks, FreeMarker template (notice I would like to generate back an xml with same structure as received one)

Again if someone can point me on the right direction, I will appreciate a lot.

If you need more information please I can post configuration files also.

Thanks for listen, David
