Hi, Gurus

I have this weird problem. I have a datawindow where I cannot open the data source. I have discovered the culprit but I don’t know why. In the SQL field list have a group_concat

SELECT …..,

group_concat(maillistdesc.descr separator ', ') mailList

FROM   clients
                . . .

                LEFT OUTER JOIN maillist ON clients.client_id = maillist.client_id
                LEFT OUTER JOIN maillistdesc ON maillistdesc.list = maillist.list
WHERE clients.client_id = :id

At run-time, all works fine and I can manipulate the fields, but If I attempt to open the data source Powerbuilder just hangs and I have to quit the Powerbuilder process in the Task Manager. In order to modify the SQL I have to edit the dw source, and either modify the source there (simple change), or delete the group_concat, then I can open the data source in the regular way. Afterwards replace the group_concat.

Any ideas?
