pq11537.st  SELECTION WITHIN CONTAINER DETAILS FAILS WITH INDEX OUT OF 
                RANGE WALKBACK

If a selectPos:notify: is sent to an EwTableList to initially select an index, 
and at some point all items are deleted from the EwTableList, you will
receive the index out of range walkback because it is trying to select
an index eventhough no items exist.

File in pq11537.st to fix the problem.
