[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-886) Instantiate jbpmConfiguration eager despite no process-definition list

[Ciro Cavani (JIRA)]

Ciro Cavani commented on JBSEAM-886:
------------------------------------

Sorry. I will try clarify my point:

When there is a xml of process definition deployed inside application, jbpm component instantiate eager jbpmConfiguration in method installProcessDefinitions through getJbpmConfiguration.

In DVD Store, the database of jBPM is set to "create-drop" and there is some xml and jbpmConfiguration (with all Persistence startup) is instantiate with the application.

On my setup, I create jBPM database for "long life" use and deploy ProcessDefinition directly on this database. No xml becouse process definition could change with application on line (no restart).

That way, jbpm component don't instantiate jbpmConfiguration on startup. Only when I call Jbpm.instance().getJbpmConfiguration().

I am requesting the same behavior for both case (xml and database deployed ProcessDefinition). This is not a bug.

> I am using ProcessDefinition deployed directly to a "long life" jBPM database (no "create-drop"). No xml with ear package. Because that, jbpmConfiguration on jbpm component is lazy instantiate.
> Actual (org.jboss.seam.core.Jbpm):
>    @Create
>    public void startup() throws Exception
>    {
>       log.trace( "Starting jBPM" );
>       installProcessDefinitions();
>       installPageflowDefinitions();

> Suggestion:
>    @Create

>    {
>       log.trace( "Starting jBPM" );
>       initJbpmConfiguration(); /*** eager despite xml */
