Hi,
Wondering if anyone can give me some help with custom workflows and tasks.
Basically I have a workflow setup via that I'm able to move a document
from state to state. As part of this I have a 'Handler' that adds a task
to certain user dashboard(s). However, I can't find out how to remove
the tasks - any help in how to do this?
I'm adding the tasks programatically via a "node-enter" event and have
tried to sort out their removal on both transition actions and
"node-leave"s, both with no success (I initiate task completion by
wapi.endWorkItem(itemId, Constants.WF_NEEDS_CLARIFICATION) and include
a dashboardActions.invalidateDashboardItems().
An example snippet of my jpdl:
<task-node name="submitted" create-tasks="false" end-tasks="false"
signal="first-wait">
<event type="node-enter">
<action class="com.xxx.workflow.SubmittedHandler"/>
</event>
<task name="Assessment" description="Document requires assessment"/>
<transition name="for-review" to="under-review"/>
<transition name="needs-clarification" to="awaiting-clarification"/>
<event type="node-leave">
<action class="com.xxx.workflow.SubmittedCleanupHandler"/>
</event>
</task-node>
And I'm creating the tasks in the SubmittedHandler as follows:
Token token = executionContext.getToken();
TaskMgmtInstance tmi = executionContext.getTaskMgmtInstance();
TaskNode taskNode = (TaskNode) executionContext.getNode();
Map tasks = taskNode.getTasksMap();
Object[] managers = (Object[]) executionContext.getVariable(
RequirementsConstants.WF_MANAGERS_LIST);
if (managers != null) {
for (Object manager : managers) {
for (Object k : tasks.keySet()) {
TaskInstance ti = tmi.createTaskInstance(
taskNode.getTask((String) k), token);
ti.start();
log.debug("Requirement: Creating and starting task ="
+ ti.getId() + " for assignee : " + manager);
ti.setActorId((String)manager);
}
}
}
Any idea on how to remove the tasks from the user dashboards?
Thanks,
Sean
