In my seam application, I have a rich:tree and some TreeNode implementations:
jsf code:
| <rich:tree id="allTasksTree" switchType="ajax"
style="width:300px"
| value="#{tasksRootNode}" var="item"
nodeFace="#{item.class.name}">
| <rich:treeNode type="org.jbpm.graph.def.ProcessDefinition">
| <h:outputText value="#{item.name}" />
| </rich:treeNode>
| <rich:treeNode type="org.jbpm.taskmgmt.def.Task">
| <h:outputText value="#{item.name}" />
| </rich:treeNode>
| <rich:treeNode type="org.jbpm.taskmgmt.exe.TaskInstance">
| <h:outputText value="#{item.toString}" />
| </rich:treeNode>
| </rich:tree>
|
TasksRootNode:
| @Stateful
| @Name("tasksRootNode")
| public class TasksRootNode implements TreeNode {
| private void InitProcessNodesMap() {
| GraphSession graphSession = ManagedJbpmContext.instance().getGraphSession();
| ...
| }
|
| ...
| }
|
TaskNode:
| @Stateful
| public class TaskNode implements TreeNode {
| ...
| private void InitTaskInstanceNodesMap() {
| GraphSession graphSession = ManagedJbpmContext.instance().getGraphSession();
| ...
| }
|
| ...
| }
|
The call to ManagedJbpmContext in RootTasksNode class is run perfectly with no problem.
But execution of TaskNode.InitTaskInstanceNodesMap raises the following (Adding
@Transactional or @Interceptors(...) to TaskNode did not help).
Any idea? I doubt if having TreeNode implementations as SFSB is a good solution. Any
idea?
