----------------------------------------

             Summary: brooklyn-client runtime panic on an app with no location
                 Key: BROOKLYN-335
                 URL: https://issues.apache.org/jira/browse/BROOKLYN-335
             Project: Brooklyn
          Issue Type: Bug
            Reporter: Geoff Macartney
            Priority: Minor


It is possible (though rare) to have an application in Brooklyn with no location, e.g. if its entities specify their own locations.  With such an application, the {{br}} client will correctly report the details with a {{br app}} command, 

{code}
br app 
Id           Name            Status    Location   
mcp7qvfh6o   Test            RUNNING 
{code}

but on requesting details for the individual application there is a panic:

{code}
$ br app mcp7qvfh6o
panic: runtime error: index out of range
