4.5 Does the framework automatically run rules for child lists or is OnChildChanged needed

I have a simple business rule that watches a child businesslistbase and checks if .Count > 0

Do I have to manually call that rule in the OnChildChanged override...or does that happen automatically because I point at the corresponding propertyinfo in the AddRule(myListPropertyInfo as core.PropertyInfo)?

Cheers,

Sean

HI,

You must trigger the rule in OnChildChanged.

I am using private backing fields for the child collections...they are marked with <NonSerialized(), NotUndoable()> to keep them from being saved in BeginEdits.

In 3.8 those collections had to be marked with WithEvents because I detected changes in the ListChanged event. Now that I am detected changes in OnChildChanged I assume I can get rid of the WithEvents now?

Thanks man!
