I have a form with parent child objects, both objects have required fields defined. I noticed an issue when a user has broken rules in the child and and parent, and clicks Save button, the children controls lose all the changes as though they get refilled.

After digging around and setting a few breakpoints, I found out that calling .Save or .CheckRules on parent BO causes Navigated even to fire (which executes my code to fill children BOs).

Is this by design? Is there a property I can set to prevent this?

Thank you.
