Workflow can't start sub-workflow

Hi folks,

I have an issue with my workflow and I am in blind way.

Sub-workflow is remote proxy workflow connected via multi-node plug-in and local workflows are running fine.

Here is output in server.log:

2015-04-16 10:48:46.978+0200 ERROR [WorkflowHandler] Unexpected error while treating workflow transition for wfExecution[8ac6cac24cc166f9014cc16a83f40005]

Does anybody konw, what does it mean?

Thanks,

Jan

Maybe this should help as well:

ERROR [WebformParameter] Error for TQGenericEnumeration: ch.dunes.model.presentation.ValueConvertionException: OGNL error : Method "call" failed for object , string (unnamed script#53)
