Ondrej Medek commented on JBIDE-4046:
-------------------------------------

So more to the 1): I thing I have found what causes the error. I think it does not matter what's inside the EAR. Just make new a JBoss server in Eclipse. Deploy some EAR project into it. Start it and stop it. Delete the JBoss server. Make a new JBoss server with the same environment as the deleted server (i.e. the same "deploy" directory, where is still deployed the EAR project.". Try to add the same EAR into this new JBoss server.

> Hi,
> I have created a new JBoss 5.0 server in the JBoss Server in the new server wizard. I have chosen to add existing EARs to the server in the wizard. I have added them and clicked "Finish". Then i see an error message "Could not save because the file has been modified since the start of the editing". I click "OK" to dissmiss this error message. So i am back in the wizard.
> So far its good, the problem is somewhere else then in the JBoss tools. 
> But if I click "< Back" button, the "Next >" and "Finish: button are disabled, so I cannot change values and finish. I can only cancel the wizard.
