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.

Ok we found the problem.
As Tihomir already said, the problem is about the version of commons codec. We found THREE different versions of commons codec in the different projects which are parts of the jBPM Installer. 1.3, 1.4 and 1.5.
It looks like jboss loads the libraries in a different order on different systems. The following output (I've got by a colleague) may help to fix the problem permanently.
> 18:32:21,749 INFO [stdout] (http-localhost-127.0.0.1-8080-1)
> >>>>>>>>>>>> commons codec location :
> vfs:/content/jbpm-gwt-console-server.war/WEB-INF/lib/org.apache.commons.codec_1.3.0.v201101211617.jar
> 18:32:21,750 ERROR

> java.lang.NoSuchMethodError:
> org.apache.commons.codec.binary.Base64.encodeBase64String([B)Ljava/lang/String;
Our temporary solution is to change the build.xml to exclude the old library on the jboss installation
> <!-- Install reporting AS7 -->
> <target name="install.reporting.into.jboss7" depends="check.birt.as7" if="birt.download" >
> <mkdir dir="${install.home}/birt"/>
> <unzip src="${install.home}/lib/birt-runtime-${birt.version.as7}.zip"
> dest="${install.home}/birt"/>
> <copy todir="${install.home}/target/jbpm-gwt-console-server-war/WEB-INF/lib">
> <fileset dir="${install.home}/birt/birt-runtime-${birt.version.as7}/ReportEngine/lib">
> <include name="**/*.jar"/>
> <exclude name="**/org.apache.commons.codec_1.3.0.v201101211617.jar"/>
> </fileset>
> </copy>
I hope it helps without causing additional problems^^
