[JBoss jBPM] - Re: Can process and task variables be defined in the process
by nbhatia
I have not seen any reference to such functionality in the manual or on the web. The jpdl schema also suggests that this is not possible. I am fairly certain that such a feature will improve the usability of jBPM as it provides an easy way to provide "personality" to processes and tasks at process definition time. Currently I see very specific handlers that can attach to a task with predefined semantics. What if I can attach a variable instead, say a variable called "form" whose value specifies the form I need to trigger in order to work on the task. Now my front-end can easily dispatch forms to take care of any task. Currently I am keeping such mappings externally and there is quite a bit of machinery needed to make this work. (I am using the process name plus the task name to create a unique key which maps to a form name. Unfortunately getting the process name from a task instance is quite expensive as it involves traversing through process instance and then process defini!
tion.)
Any thoughts from the committers?
Thanks.

[JBoss jBPM] - Redeploying of deployed processes
by Turanyi
Hi.
When process is deployed and application server is restarted then application server redeploy this process again.
There an issue because app server does not work it out.

So process does not working. You cannot start any instance. You have to deploy process again manualy.
