APEX

I read experts comments on when apex issues commit. But still have a question:

I have pl/sql process which runs at "On submit and before computation". It does not change any session state. It just includes direct insert and update statements.

I am not issuing any explicit commit. And things seem to be working fine-I mean DMLs are being auto committed in any case.

But still want to get my question answered:

If a validation fails or if another process which is fired at "After submit" fails , will the insert and update statements be still committed?

In what scenario, the DMLs will not be committed?
