[JBoss jBPM] - create-task="false" does not wok
by ahmadyan
Hi,
I wanted to dynamically create my tasks, hence I put this task-node:
<task-node create-task="false" name="task-node-1" >
<assignment class="MyRoleAssignmentHandler" config-type="bean">
RoleName
<action class="CreateMultiTask"
config-type="bean"
name="createMultiplyRepairTask"
create-task="false">
</task-node>
with the following actionHandler:
public class CreateMultiTask implements ActionHandler {
public void execute(ExecutionContext executionContext) throws Exception {
Token token = executionContext.getToken();
TaskMgmtInstance tmi = executionContext.getTaskMgmtInstance();
TaskNode taskNode = (TaskNode) executionContext.getNode();
// Assignee:
Vector roleInstanceSet = (Vector) tmi.getProcessInstance().getContextInstance().getVariable("__assignee");
if ( roleInstanceSet == null ) throw new Exception("Role instance set is null . ..");
// Task
Task task = taskNode.getTask( tmi.getProcessInstance().getContextInstance().getVariable("__task").toString());
for( Long ri : roleInstanceSet ){
TaskInstance ti = tmi.createTaskInstance(task, executionContext);
ti.setActorId("$RI_" + ri.toString());
}
}
}
it does as it supposed to do, it creates some task based myActionHandler but also it create one additional task than expected ( the default task for task-node, which is defined in the task tag. ) it seems that create-task="false" does not work.
any comments or suggestion are welcome.

[JBoss jBPM] - Re: Id of process starter
by yozh1k
Thx for answer first of all.
I tried such way. But it's not working.
<process-definition xmlns="" name="todo">
| <swimlane name='initiator'>
| <assignment actor-id="#{actor.id}"/>
| </swimlane>
|
| <start-state name="Start">
| <task name= 'taskforinitiator' swimlane='initiator'/>
| <transition to="UserProcessNum"></transition>
| </start-state>
|
|
| <task-node name="todo">
| <task name="todo" description="#{todoList.description}">
| <assignment actor-id="#{actor.id}"/>
| </task>
| <transition to="done"></transition>
| </task-node>
|
| <decision name="UserProcessNum">
| <handler class="org.jboss.decisiontest.UserProcessNumHandler"> </handler>
| <transition to="todo" name="ok"></transition>
| <transition to="done" name="2much"></transition>
| </decision>
|
|
| <end-state name="done"></end-state>
|
|
| </process-definition>
public class UserProcessNumHandler implements DecisionHandler {
| public String decide(ExecutionContext ec){
| String acId = ec.getProcessInstance().getTaskMgmtInstance().getSwimlaneInstance("initiator").getActorId();
| return "ok";
|
| }
| }
|
And result is...
