<div class="jive-rendered-content"><p>Using jBPM 5.4, Hibernate 4, JPA2 I have a rule in which I want to create an object and then start a process with a facthandle to this object as one of the variables.  (FYI, I'm passing the facthandle because I want the process to retract the object I created before it ends.  </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The issue is that right after my rule fires (right after the output, "started process: 123" - see below) I get the following error:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="font-family: courier new,courier;"><strong>    java.lang.IllegalArgumentException: IOException while storing process instance 123: org.drools.common.NamedEntryPoint</strong></span></p><p><span style="font-family: courier new,courier;"><strong>    org.jbpm.persistence.processinstance.ProcessInstanceInfo.update(ProcessInstanceInfo.java:207)</strong></span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>If I insert null or a string instead of the fact handle, everything works fine.  </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>MY GOAL:  I am inserting objects into working memory and based upon the object, if a related process already exists, I will send a signal to it, if a related process does not already exist I want to create/start one.  I use a "MarkerBean" to determine whether or not a related process already exists.  When a process ends, it needs to remove the related MarkerBean.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The following rule is giving me the exception.  Here, an object (MyEventBean) has been inserted and I am looking to see if there is a corresponding MarkerBean.  Then, I create the process and new markerbean if necessary:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="font-family: courier new,courier;">rule "TestRule4"</span></p><p><span style="font-family: courier new,courier;">  no-loop true</span></p><p><span style="font-family: courier new,courier;">  dialect "java"</span></p><p><span style="font-family: courier new,courier;">when</span></p><p><span style="font-family: courier new,courier;">   $meb: MyEventBean(style matches ".*western.*")</span></p><p><span style="font-family: courier new,courier;">   not ($mb : MarkerBean(title matches $meb.getTitle()))</span></p><p><span style="font-family: courier new,courier;">then</span></p><p><span style="font-family: courier new,courier;">  // first get the fact handle and pass it to the process</span></p><p><span style="font-family: courier new,courier;">  MarkerBean $mb = new MarkerBean();</span></p><p><span style="font-family: courier new,courier;">  Object factHandle = kcontext.getKnowledgeRuntime().insert($mb);</span></p><p><span style="font-family: courier new,courier;">  System.out.println("got object:"+factHandle.getClass().getName());   <=== prints org.drools.common.DefaultFactHandle</span></p><p><span style="font-family: courier new,courier;">  java.util.Map<String,Object> variables = new java.util.HashMap<String,Object>();</span></p><p><span style="font-family: courier new,courier;">  variable.put("markerHandle",factHandle)</span></p><p><span style="font-family: courier new,courier;">  WorkflowProcessInstance pi = (WorkflowProcessInstance)kcontext.getKnowledgeRuntime().createProcessInstance("test.SimpleProcess", variables);</span></p><p>  </p><p><span style="font-family: courier new,courier;">  //store the new processinstance in the new MarkerBean (so I can later signal it)</span></p><p><span style="font-family: courier new,courier;">  $mb.setTitle($meb.getTitle());</span></p><p><span style="font-family: courier new,courier;">  $mb.setProcessInstanceId(pi.getId());</span></p><p><span style="font-family: courier new,courier;">  update($mb)</span></p><p>  </p><p><span style="font-family: courier new,courier;">  kcontext.getKnowledgeRuntime().startprocessInstance(pi.getId());</span></p><p><span style="font-family: courier new,courier;">  System.out.println("started process "+pi.getId());</span></p><p><span style="font-family: courier new,courier;">end</span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>For grins I added DefaultFactHandle ( to my persistence.xml, didn't help.  As I mentioned, if I add a plain string rather than the factHandle, everything works.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Does anyone see anything here that could be causing a problem?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thanks vm!</p><p>-J</p></div>
