Asccociation / DeAssociation

Hi Mendix Community, I have two entities, Entity A(Single Object) and Entity B(List) where Enitiy A is associated to Entity B using a  1 - *(One To Many Relationship). I have some filters which refreshes the association every time i click on the dropdowns. Is there faster way to de-associate Entity B with Entitiy A other than using a Loop.  Can we implement this using a Java Action or some inbuilt API available in Mendix.   Thanks, Karthik SM

If it does not need to be a 1-* association you could use a *-* association and just clear the list of associated objects in A. But you may loose some comfort you have with the 1-* association.

How many objects need to be deassociated? I think it depends on this question.
