How to manlipulate PrincipalGroupRelation in code

[Former Member]

Hi ,
The UserGroup was updated, which should not be because I've changed nothing but the association with a Customer, and I can not find a way to manlipulate the PrincipalGroupRelation in code.
Is there anyway to manlipulate the PrincipalGroupRelation in code, or disable the update for UserGroup during the changing of Customer's groups.

Between UserGroup and Customer is a many-to-may relation, and one of the features of such a relation is that both ends are updated when one end changes. You will always be able to navigate to all customers of a group, or to all groups of a customer, regardless where you change the relation.

But, there are some ways to suppress at least the update of the modifiedtime of the Customer or UserGroup using following property:

 relation. PrincipalGroupRelation.markmodified = false 

This works with every relation, the syntax is relation.<relationname>.markmodifed=false|true
