[jboss-user] [JBoss jBPM] - taskform in the start activity - form vars dont get persiste

[lalitjava]

We are using JBPM v4 for a pilot at one of our institute labs. 
Since it's a pilot, we are not creating a separate UI to access the TaskService etc. We are instead leveraging the taskforms capability and using FTL templates for forms at different points in the workflow.

One issue that we have run into is that if we have a form associated with the start activity, then none of the form params ( posted via HTTP when the workflow is started through the console) are being persisted into the JBPM4_VAR table till we introduce a halt in the workflow via a task associated with a user/group.

Net effect of this seems to be that if you try to reference any of the form params before this task in the workflow, we get nulls.

After the task (any task with a halt), the form params become available as process instance variables and can be used in the workflow..

Is this an issue that others have run into? Or maybe we are doing something wrong?

Here's the jpd.xml snippet..

This works ..(note the halt we introduce via a manager_approval before we try to reference the hr_subcategory form variable in the is_lab_approval_needed decision activity).
Trying to directly go from start to is_lab_approval_activity fails since hr_subcategory is resolved to null (we get a NPE).

Also, one more quick question - we noticed that the JBPM4_HIST_VAR table never gets populated. The JBPM4_VAR table stores the process variables only as long as the process is active..If we dont want to create our own audit repo and leverage what JBPM4 provides out of the box, where do we see the process variables (we need some of these for an audit trail)?
