    Getting a "A RuleFlowProcess cannot have more than one start node!"

    Jett Gamboa Newbie

      We currently have a process that I am attempting to load into a KnowledgeBuilder. The process has 3 embedded subprocesses, each one having a start node. The main process has one start node and another message start node. When loading into KnowledgeBuilder, I am getting the following exception:

       

      java.lang.IllegalArgumentException: A RuleFlowProcess cannot have more than one start node!

                at org.jbpm.ruleflow.core.RuleFlowProcess$WorkflowProcessNodeContainer.validateAddNode(RuleFlowProcess.java:81)

                at org.jbpm.workflow.core.impl.NodeContainerImpl.addNode(NodeContainerImpl.java:42)

                at org.jbpm.workflow.core.impl.WorkflowProcessImpl.addNode(WorkflowProcessImpl.java:63)

                at org.jbpm.bpmn2.xml.AbstractNodeHandler.end(AbstractNodeHandler.java:110)

       

       

      A little Googling led me to this issue in JIRA: https://issues.jboss.org/browse/JBPM-3586

       

      I tried loading the multiple-incomes.bpmn attached in the JIRA issue and I am getting the same error. The resolution does say that it is implemented as of June 6, 2012 and should make it's way to JBPM 5.4 with a note: "support for multiple start events with restriction that only one can be with no event definition". I attempted to use the snapshot build (5.4.0-SNAPSHOT) by adding the following to my pom.xml

       

          <repositories>

              <repository>

                  <id>repository.jboss.org</id>

                  <name>JBoss Repository - Snapshots</name>

                  <url>http://snapshots.jboss.org/maven2</url>

                  <layout>default</layout>

                  <releases>

                      <enabled>false</enabled>

                  </releases>

                  <snapshots>

                      <enabled>true</enabled>

                      <updatePolicy>never</updatePolicy>

                  </snapshots>

              </repository>

          </repositories>

       

      I am however getting the same error when I load the file. Has anyone experienced a similar issue or at least can provide information on how to get a version that has the fix for this?

       

      Thanks in advance the help.

       

      Message was edited by: Jett Gamboa - attaching an image of the process model in question. Note the two embedded subprocesses with each one having it's own <startEvent>. It may be noteworthy to add that I can't get this to load on the new Eclipse BPMN editor. (The file was created using the open source Signavio core editor).
