                 Key: JBPM-2717
                 URL: https://jira.jboss.org/jira/browse/JBPM-2717
             Project: jBPM
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: jBPM 4.3
         Environment: Windows Vista, java 1.6, jboss 4.2.2.GA
            Reporter: Per Christian Henden


I ran into a problem with accessing boolean properties of an eventListener.
I've attached a patch to trunk of ./modules/pvm/src/test/java/org/jbpm/pvm/internal/wire/ObjectWireTest.java that adds a test that exposes this problem.

Basically, the example below fails with the error 
"org.jbpm.pvm.internal.wire.WireException: couldn't initialize object 'null': couldn't find property setter setCreateXml for value true"

JPDL-fragment:
     <event-listener expr="#{stateApprovalAction}">
                <property name="createXml">
                    <true/>
                </property>
            </event-listener>

Java-fragment:
   public void setCreateXml(boolean createXml) {
        this.createXml = createXml;
    }

Workaround: changing the Java-side to use a Boolean instead of a boolean for the method parameter. 

While there is a workaround,  I will still suggest supporting both Boolean and boolean-based setters.
