Steps to reproduce:
1.  In AppServer, install a second BPEL Service Engine and start it
2.  Unzip attached project
3.  Right-click on SampleProjectsMultiDepJBI and select 'Properties'
4.  In the Project Properties Window, select 'Packaging Project'
5.  Click on the Update button
6.  Select the SynchronousSample.jar Service Assembly artifact.  
7.  Assign the new BPEL SE you just installed to it, so that it is using a 
different BPEL SE than the others.
8.  Click OK - window will close
9.  Reopen the window by right-clicking on the JBI project and 
select 'Properties'

Result:  When you go back to the Packaging Project screen, you will notice that 
none of the updates you made were saved.  In addition the jbi.xml was not saved 
to reflect any of the changes that were previously made.

Expected Result:  The SynchronousSample.jar Deploymnet Target Component should 
have been saved to the BPEL SE chosen.
