                 Key: JBIDE-3490
                 URL: https://jira.jboss.org/jira/browse/JBIDE-3490
             Project: Tools (JBoss Tools)
          Issue Type: Bug
    Affects Versions: 3.0.0.cr1
            Reporter: Nick Boldt


Tested with JBoss Dev Studio Version: 2.0.0.CR1, Build id: R200812221144

Steps to repro:

1. Install JBDS.
2. download http://www.jboss.org/downloading/?projectId=jbossjbpm&url=http://downloads.sourceforge.net/jbpm/jbpm-installer-3.3.0.GA.jar
3. `java -jar jbpm-installer-3.3.0.GA.jar`. I installed into ~/jbpm-3.3.0.GA
4. New > Other > Process Project
5. Go into src/main/jpdl/simple and open processdefinition.xml with jBPM Graphical Process Designer
6. Add a couple nodes, then connect them to the existing flow.
7. Switch to Source tab. I had this:

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

<process-definition
  xmlns="urn:jbpm.org:jpdl-3.2"
  name="simple">
   <start-state name="start">
      <transition name="to_state" to="first">
         <action name="action" class="com.sample.action.MessageActionHandler">
            <message>Going to the first state!</message>
         </action>
      </transition>
<transition to="mail-node1" name="to mail-node1"></transition>
   </start-state>
   <state name="first">
      <transition name="to_end" to="end">
         <action name="action" class="com.sample.action.MessageActionHandler">
            <message>About to finish!</message>
         </action>
      </transition>
   </state>

<task-node name="task-node1">
<transition to="end"></transition>
</task-node>

<mail-node name="mail-node1">
<transition to="task-node1"></transition>
</mail-node>
   <end-state name="end"></end-state>
</process-definition> 

8. Click [x] on editor tab to close it. You should be prompted to save dirty editor. Save.

9. Reopen editor. Move some nodes around. Note editor is again in 'dirty' state.

10. Click [x] on editor tab to close it. This time you're not prompted to save (because the changes are in a different file, gpd.xml). 

11. Repeat steps 9-10, verifying that changes to layout are saved into gpd.xml.

** Surely these changes to UI layout shouldn't be automatically written without the user's confirmation? **

--

11. Open gpd.xml using xml editor. Switch to Source tab and note (x,y) coords for the start node. 

12. Reopen processdefinition.xml in jBPM Graphical Process Designer editor. Move the start node. Note editor is again in 'dirty' state, as in step 9 above.

13. Click [x] on editor tab to close it. Still not prompted, as in step 10. Close gpd.xml too. 

14. Reopen gpd.xml. This time, nothing has changed!

** Surely layout changes shouldn't just vanish if the gpd.xml file's open in parallel with the jBPM Graphical Process Designer editor? **
