[jboss-user] [jBPM] - Timer BoundaryEvent and User Tasks

Jett Gamboa [https://community.jboss.org/people/jett] created the discussion "Timer BoundaryEvent and User Tasks" To view the discussion, visit: https://community.jboss.org/message/743232#743232 -------------------------------------------------------------- Does anyone know if Timer BoundaryEvents can work when attached to User Tasks? I created a simple process model (see attached) with the said scenario and KnowledgeBuilder is unable to parse the process file. java.lang.IndexOutOfBoundsException: Index: 0, Size: 0           at java.util.ArrayList.RangeCheck(ArrayList.java:547)           at java.util.ArrayList.get(ArrayList.java:322)           at org.jbpm.bpmn2.xml.ProcessHandler.linkBoundaryEvents(ProcessHandler.java:333)           at org.jbpm.bpmn2.xml.ProcessHandler.end(ProcessHandler.java:144)           at org.drools.xml.ExtensibleXmlParser.endElement(ExtensibleXmlParser.java:417)    ... I traced into source the issue and it fails in the following method from within *ProcessHandler.java*     public static void linkBoundaryEvents(NodeContainer nodeContainer) {         for (Node node: nodeContainer.getNodes()) {             if (node instanceof EventNode) {                 final String attachedTo = (String) node.getMetaData().get("AttachedTo");                 if (attachedTo != null) {                           String type = ((EventTypeFilter) *((EventNode) node).getEventFilters().get(0)).getType();* There appears to be no issues attaching Timers to other types of tasks. Thanks in advance for any insights into this. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/743232#743232] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
