The DBISAM documentation says this error should never occur and to report all instances to tech support so here I am.

I receive this error when doing something similar to the following

Query1.Open;
Query1.BeginCachedUpdates;
Query1.Filter := 'SomeIntegerField = ' + IntToStr(22);
Query1.Filtered := True;
Query1.Edit;
Query1['SomeMemoField'] := 'blah';
Query1.Post;
Query1.ApplyCachedUpdates; // exception thrown here

If I insert the line

Query1.Filtered := False;

just before the ApplyCachedUpdates no exception is thrown.

Thanks very much,

This is with DBISAM 4.34 build 4

Lachlan,

Sounds like a bug, and I'll make sure that this is fixed in the next build.
For now, keep using the described workaround.

Thanks,
