I am trying to print out the processes defined in the JbpmContext
and their nodes.
I get the message
failed to lazily initialize a collection of role:
org.jbpm.graph.def.ProcessDefinition.nodes, no session or session was closed
The bean
public class ProcessManagerBean
{
@Logger
private Log logger;
@In(create=true)
JbpmContext jbpmContext;
@DataModel
private List processList;
@DataModelSelection
@Out(required=false)
private ProcessDefinition process;
@PersistenceContext(type=EXTENDED)
private EntityManager em;
//not used yet
@Out(required=false)
private List nodeList;
@Factory("processList")
public void findMessages()
{
GraphSession graph = jbpmContext.getGraphSession();
processList=graph.findLatestProcessDefinitions();
}
....
A fragment from the page is
<h:dataTable id="someTable" var="proc" value="#{processList}"
rendered="#{!empty processList}">
<h:column>
<f:facet name="header">
<h:outputText value="Name"/>
</f:facet>
<h:commandLink value="#{proc.name}"
action="#{processManager.select}"/>
</h:column>
</h:dataTable>
<h3><h:outputText value="#{process.name}"/></h3>
<h3><h:outputText value="#{process.nodes}"/></h3>
The exception is caused by adding the last line
My guess is that the jbpm session is not using an extended persistence context
If thats the case how do I get it to use one.
If not what is the problem.
Thanks
