I have a base form (private datasession, optimistic buffering) that I use for handling data. Deletions and updates are wrapped by transactions. All works well but when I add a view to the form that is being used in a different datasession. For some large lookups I was trying to issue

USE xxx in 0 norequery OtherForm.DataSessionID

If I do this every time a hit a ROOLBACK I get an exception error (0x0000005 0x0050f6bc) and it is back to windows.
Anybody any ideas? For the time being I am opening the views in the local datasession without much of a performance degradation but I am curious as to the hows and whys.

Thanks
