>                 Key: JBSEAM-4629
>                 URL: https://jira.jboss.org/browse/JBSEAM-4629
>             Project: Seam
>          Issue Type: Bug
>    Affects Versions: 2.2.1.CR1
>            Reporter: Tihomir Surdilovic
>            Assignee: Tihomir Surdilovic
>             Fix For: 2.2.1.CR2
>
>
> When injecting org.jboss.seam.bpm.ProcessInstance in a Seam components the code ends up in the following code snipped of this class:
> ********
> if (processId!=null)
>            {
>               //TODO: do we need to cache this??
>               return ManagedJbpmContext.instance().getProcessInstanceForUpdate(processId);
>            }
> ********
> the org.jbpm.JbpmContext#getProcessInstanceForUpdate(processId) method will get a process instance from the db and will register it for auto-save. It will then be saved automatically at the close() .
> Continuous registering for auto-save can cause performance issues as when the jbpmContext closes it will save all instances in the autoSaveProcessInstances list which can be huge.
> The proposed fix is to change to the code to:
> if (processId!=null)
>            {
>               return ManagedJbpmContext.instance().getProcessInstance(processId);
>            }
