Hi All,
I want to refer to a value from a bean in a jbpm decision node, but not able to get that using EL. I can write the decision handler and do it that way, but i would prefer using the EL. Can anyone help me in that?

Here is what i am doing.

<?xml version="1.0" encoding="UTF-8"?>
<process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="http-demo-process">
 <swimlane name="initiator">
 <assignment actor-id="manager" />
 </swimlane>
 <start-state name="start">
 <transition to="call action"></transition>
 </start-state>
 <node name="call action">
 <action class="com.sample.action.MessageActionHandler">
 <message>First message</message>
 </action>
 <transition to="hasMessage?"></transition>
 </node>

 <decision name="hasMessage?" expression="#{( ??????? ? 'true' : 'false')}">
 <transition name="true" to="post data"></transition>
 <transition name="false" to="end"></transition>
 </decision>
 <node name="post data">
 <action class="com.sample.action.PostActionHandler">
 </action>
 <transition to="end"></transition>
 </node>
 <end-state name="end"></end-state>
</process-definition>

and here is the bean which i created.

package com.sample.bean;

import java.io.Serializable;
public class MyVariableBean implements Serializable{

private static final long serialVersionUID = 1L;
private Boolean myValue = true;

public MyVariableBean() {}
public Boolean getMyValue()
{
return myValue;
}

public void setMyValue(Boolean paramVal)
{
myValue = paramVal;
}
}

The value of MyValue is set in Message Action Handler...but then how should I refer to the MyValue in decision node EL??

Please help..

thanks
