"Access to variable via EL ?" To view the discussion, visit: http://community.jboss.org/message/546401#546401 -------------------------------------------------------------- Hi, My need seems to be pretty simple ! First : I'have a task, owned by a user. At the end of the task, I want to record the userid of the owner into a process variable using : public class TaskAssigneeEventListener implements EventListener { ... @Override public void notify(EventListenerExecution execution) throws Exception { TaskService taskService = processEngine.getTaskService(); Task task = taskService.createTaskQuery().processInstanceId(execution.getProcessInstance().getId()).uniqueResult(); if (task == null) { logger.warn("No task found for ProcessInstance {}", execution.getProcessInstance().getId()); } else { logger.trace("task name {} ; assignee ", task.getName(),task.getAssignee()); execution.createVariable("MyLastTaskAssignee", task.getAssignee()); } } } Second : I want to retreive that value into an assignment handler to assign that task to that user : public class MyAssignementHandler implements AssignmentHandler { //Field I want to inject from my process private String previousUserId; @Override public void assign(Assignable assignable, OpenExecution execution) throws Exception { logger.trace("Value of previousUserId {} ", previousUserId); if (previousUserId != null) { assignable.setAssignee(previousUserId); } else { logger.warn("No assignee from the last task !!"); } } } My tasks : <task assignee="john" g="174,75,92,52" name="taskUser"> <on event="end"> <event-listener expr="#{taskAssigneeEventListener}"> </event-listener> </on> <transition name="to taskManager" to="taskManager" g="-126,-24" /> </task> <task g="337,173,92,52" name="taskManager"> <assignment-handler expr="#{myAssignementHandler}"> <field name="previousUserId"> <object expr="#{variables['MyLastTaskAssignee'}"/> </field> </assignment-handler> <transition name="to end1" to="end1" g="-65,-24" /> </task> Is it better to understand my need ?
