I am surprised that AfterPost is not being called - but then I am not
that familiar with the TDataset based components.

However I do think Helen was correct in questioning the fact that you
are trying to do the commit/rollback in AfterPost/AfterCancel.

Rather than going to the trouble of forcing the master dataset into
edit mode - just so it can be posted and force a commit - supply
commit/rollback buttons to the transaction.

When I setup a form for the user I generally dont give then
post/cancel buttons attached to the dataset, I give them save/cancel
buttons attached to the transaction. It is much simpler and the
transaction will automatically post or cancel any datasets that have
outstanding changes.

Does this help?
