Alex Pavlov [http://community.jboss.org/people/rushproject] created the discussion "Timer boundary event on WorkItemNode" To view the discussion, visit: http://community.jboss.org/message/600495#600495 -------------------------------------------------------------- jBPM 5 does not allow attaching timer boundary events to WorkItemNode. The following fragment: <receiveTask completionQuantity="1" id="_2_1_21" implementation="##WebService" instantiate="false"                      isForCompensation="false" messageRef="ID_30607364_7317_2206_0052_000400200024"                      name="Receive confirmation" startQuantity="1">             <incoming>_2_1_22</incoming>             <outgoing>_2_1_25</outgoing>         </receiveTask>         <boundaryEvent attachedToRef="_2_1_21" id="_2_1_21_1" name="48 Hours">             <outgoing>_2_1_21_2</outgoing>             <timerEventDefinition id="ID_22607364_7317_2206_0052_000400200027">                 <timeCycle>P48H</timeCycle>             </timerEventDefinition>         </boundaryEvent> results in exception: java.lang.ClassCastException: org.jbpm.workflow.core.node.WorkItemNode cannot be cast to org.jbpm.workflow.core.node.CompositeContextNode while executing this line (ProcessHandler.java, line #280): CompositeContextNode compositeNode = (CompositeContextNode) attachedNode; Both CompositeContextNode and WorkItemNode extend StateBasedNode class, which defines addTimer() - the only method called from ProcessHandler while processing timer boundary event. In other words, changing the offending line to StateBasedNode compositeNode = (StateBasedNode) attachedNode; will compile and will not result in run time exception. However, will it run? In other words, would it be sufficient to enable timer boundary events for work item nodes? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/600495#600495] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
