                 Key: JBIDE-4046
                 URL: https://jira.jboss.org/jira/browse/JBIDE-4046
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: JBossAS
    Affects Versions: 3.0.0.GA
         Environment: eclipse.buildId=M20090211-1700

            Reporter: Ondrej Medek
            Priority: Minor

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.
