For them I use a tasklistener expression and call my service from there, the problem I have is that if you invoke the create event, acitiviti throws an exception indicating that the task with ID xxxx does not exist. and if you invoke the assigment event will not run until someone claims the work as their own.</SPAN><BR /><BR /><SPAN>The code</SPAN><BR /><BR /><PRE class="language-none line-numbers"><CODE>public class TaskGroupAllocatorImpl implements TaskGroupAllocator{<BR />&nbsp;&nbsp;&nbsp;@InjectService("taskService")<BR />&nbsp;&nbsp;&nbsp;private TaskService taskService;&nbsp;&nbsp;&nbsp;<BR />&nbsp;&nbsp;&nbsp;@Inject<BR />&nbsp;&nbsp;&nbsp;private EntityManager em;&nbsp;&nbsp;&nbsp;<BR />&nbsp;&nbsp;&nbsp;public void setAssigned(String taskId, Integer groupFk) throws Throwable {<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;String usuarioFinal = null;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Long noTareas = 0l;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;String queryUsers = "select e.systemuserfk from systemusergroup e where e.systemgroupfk = " + groupFk;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;SystemGroup sg = em.find(SystemGroup.class, groupFk);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Query qU = em.createNativeQuery(queryUsers);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;List&lt;Object&gt; usuarios = qU.getResultList();&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;usuarioFinal = "" + usuarios.get(0);<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;for (Object systemUserFk : usuarios) {<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Long tmpNoTareas = 0l;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;TaskQuery tq = taskService.createTaskQuery().taskAssignee(systemUserFk.toString());<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if(tq != null){<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;System.out.println("User: " + systemUserFk + " has " + tq.count() + " tasks.");<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;tmpNoTareas += tq.count();<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if(tmpNoTareas &lt; noTareas){<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;usuarioFinal = systemUserFk.toString();<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;noTareas = tmpNoTareas;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;taskService.setAssignee(taskId, usuarioFinal);<BR />&nbsp;&nbsp;&nbsp;}<BR />}<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN></CODE></PRE><BR /><SPAN>And I call this service from the task listener expression:</SPAN><BR /><BR /><PRE class="language-none line-numbers"><CODE>${TaskGroupAllocator.setAssigned(task.getId(),2)}<SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN></CODE></PRE></BODY></HTML> Wed, 11 Apr 2012 16:29:38 GMT adrianbj 2012-04-11T16:29:38Z Assign a user to a task from a tasklistener expression https://connect.hyland.com/t5/alfresco-archive/assign-a-user-to-a-task-from-a-tasklistener-expression/m-p/104982#M73369 Greetings to the community, I have a task that is assigned to a group, but I want when creating the task is called a service charge to verify the user with fewer tasks to be assigned to this new task.
