IsDirty debugging in object graph

[Chicagoan2016]

We have an object graph with a root object and several child objects.
This is an old project where we manually populate the object graph from UI.
We save the object graph but before closing we read the values from UI again and make sure there aren't any unsaved changes. Sometimes, because of a bug in our code we get 'Dirty' message from our object graph. We set breakpoints and find the bug but.. I was wondering if there is an easy way to find such bugs, maybe, conditional breakpoints etc.?
Fellow csla developers!!

Kind Regards
