             Summary: [Broker-J] [Query] [WMC] Ordering connections tables by 
port column fails with '422 - The orderBy expression at position '0' is 
unsupported'
                 Key: QPID-8104
                 URL: https://issues.apache.org/jira/browse/QPID-8104
             Project: Qpid
          Issue Type: Bug
          Components: Broker-J
            Reporter: Keith Wall


Ordering the connections table on the virtualhost tab by port ends with error 
{{422 - The orderBy expression at position '0' is unsupported}}.

The select clause in question uses an alias {{port.name AS port}}.  In general 
the ability to express an the order by in terms of column aliases is supported 
however,  the issue here seems to be that {{port}} is ambiguous and could refer 
to the {{Collection#port}} attribute or the alias.

The user of the query API can workaround by using a column number, or specify 
the column's expression rather than alias.

I have not looked into this further.
