Subject Re: [IBO] Refreshing a IBODataset
Author G. Allen Casteran

Do you have an OnPrepareSQL event linked to the dataset??

Are you watching to see if your AV occurs in there??

Perhaps you are doing something in that event handler to reference an
invalid variable.

If you do not have an OnPrepareSQL event then I do not see the need to call
InvalidateSQL to do the refresh.
