Help getting a condition to work

[earniedyke]

Greetings all!!!!

I have been trying all day to get, what I think, is a simple process to work. I can never get it to think the account is NOT locked. No matter what value I set the locked variable to it always takes the default transition. I have tried every style of condition I could find referenced in this forum all to no avail.

Any and all help would be appreciated.

processdefinition.xml

<?xml version="1.0" encoding="UTF-8"?>

<process-definition
 xmlns="urn:jbpm.org:jpdl-3.1" name="test2">
 <start-state name="BeginLogin">
 <transition name="toCheckForLock" to="CheckForLockedAccount"></transition>
 </start-state>
 <end-state name="End"></end-state>
 <decision name="CheckForLockedAccount">
 <transition name="Account is locked" to="AccountIsLocked"></transition>
 <transition name="Account is not locked" to="AccountIsNotLocked">
 <condition expression="#{contextInstance.variables['locked'] == 'N'}"/>
 </transition>
 </decision>
 <node name="AccountIsLocked">
 <controller>
 <variable name="message">Is</variable>
 </controller>
 <transition name="toEnd" to="End"></transition>
 </node>
 <node name="AccountIsNotLocked">
 <controller>
 <variable name="message">Is NOT</variable>
 </controller>
 <transition name="toEnd" to="End"></transition>
 </node>
</process-definition>

test case:

package com.sample;

import java.io.FileInputStream;

import junit.framework.TestCase;

import org.jbpm.*;
import org.jbpm.graph.def.ProcessDefinition;
import org.jbpm.graph.exe.ProcessInstance;

public class SimpleProcessTest extends TestCase {
 public void testSimpleProcess() throws Exception {
 JbpmConfiguration cfg = JbpmConfiguration.getInstance();
 JbpmContext ctx = cfg.createJbpmContext();
 try {
 FileInputStream fis = new FileInputStream("processes/test2/processdefinition.xml");
 ProcessDefinition processDefinition = ProcessDefinition.parseXmlInputStream(fis);
 ctx.deployProcessDefinition(processDefinition);

 ProcessInstance instance = ctx.getGraphSession().findLatestProcessDefinition("test2").createProcessInstance();

 instance.getContextInstance().setVariable("locked","N");

 instance.signal();
 System.out.println(instance.getContextInstance().getVariable("message") + " Locked? " + instance.getContextInstance().getVariable("locked"));
 } finally {
 ctx.close();
 cfg.close();
 }
 }

}

try this:

<condition expression="#{locked == 'N'}"/>

Heyi earnie,

Is this allowed ?

 <controller>
 <variable name="message">Is</variable>
 </controller>

I think variable tag can only declare the variable.

If you can post the exception that will be helpful to us.

cheers!

Thanks for the help. You are correct the variable in the controller was not valid. This is what I have now that works:

<?xml version="1.0" encoding="UTF-8"?>

<process-definition
 xmlns="urn:jbpm.org:jpdl-3.1" name="test2">
 <start-state name="BeginLogin">
 <transition name="toCheckForLock" to="CheckForLockedAccount"></transition>
 </start-state>
 <end-state name="End"></end-state>
 <decision name="CheckForLockedAccount">
 <transition name="Account is locked" to="AccountIsLocked"></transition>
 <transition name="Account is not locked" to="CheckPassword">
 <condition expression="#{contextInstance.variables['locked'] == 'N'}"/>
 </transition>
 </decision>
 <node name="AccountIsLocked">
 <script>executionContext.getContextInstance().setVariable("message","Is");</script>
 <transition name="toEnd" to="End"></transition>
 </node>
 <node name="CheckPassword">
 <script>executionContext.getContextInstance().setVariable("message","Is NOT");</script>
 <transition name="toEnd" to="End"></transition>
 </node>
</process-definition>
