Hi,

I'm not very experienced with IBO. I can't figure out why when I click
on the update bar attached to my detail table a new row isn't inserted
into the detail table. The master-detail relationship is working in
the sense that changing the master record causes an update to the
detail grid.

I'm using BCB6 and am having trouble debugging as the symbols for
IB_components.pas are messed up past a certain part in the file, but I
was able to discover that a breakpoint set for IB_Grid.InvalidateRow
is hit, and then I can see the call stack. I compared that call stack
to the same process in the example program MasterLinks (where a row is
inserted) and it seems the difference is in what code is attached to
the events of TIB_Datalink.DoDataChange.

I think I've verified that the row is added to the dataset and the
foreign key's value is being set as well.

Here's the call stack for my program (reversed to make it easy to
compare with the example program):
