I try to use this query but there's a problem with the condition token.parent is not null, because if the token is the root token the parent is null... I don't understand why this condition is in the query. I think a select DISTINCT node is also needed. <query name="GraphSession.findActiveNodesByProcessInstance"> | <![CDATA[ | select 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.parent is not null | and token.end is null | ]]> | </query> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4128412#...
