[jbpm-issues] [JBoss JIRA] Commented: (JBPM-1133) the query findActiveNodesByProcessInstance doesn't find active nodes in the root token

David Roberts commented on JBPM-1133:
-------------------------------------

I also noticed I wasn't getting any Node objects returned when calling: graphSession.findActiveNodesByProcessInstance(processInstance);

I have taken your advice above and modified the query in my app as you suggested, and just called it myself where I need it.

I used the following code to get the nodes:

//-------------------------------------------------------------------------------------------------------------------------------------------------
Query query = jbpmContext.getSession().createQuery("select distinct node from org.jbpm.graph.def.Node node," +
													 "org.jbpm.graph.exe.Token token," +
													 "org.jbpm.graph.exe.ProcessInstance processInstance " +
													 "where token.processInstance = :processInstance " +
													 "and token.node = node " +
													 "and token.isSuspended != true " +
													 "and token.end is null");
query.setEntity("processInstance", processInstance);
List nodes = query.list();
//-------------------------------------------------------------------------------------------------------------------------------------------------

 It seems to be working nicely now - thanks.

> the query findActiveNodesByProcessInstance has the condition "token.parent is not null", but if the token is the root token his parent is null.
> the query needs certainly also a "distinct".
