jBPM Question
I have processes running in jBPM. They are kicked off by quartz and do not require user interaction.
I am trying to wrap them with seam so that user interaction is possible even though it isn't required.
I have been running into some problems with the standalone processes in my seam app.
I created a page with a button to kick off the process.
The process starts and transitions to the first node. The appropriate method is called. However the processInstance, jbpmContext, businessProcess are all null.
Does this use case make sense for seam's jbpm support? Should I leave the standalone process deployed as a jBPM par and use seam only for the user interaction?
Thanks,
Jeremy
