Hello There,

I have a multi-values feature named 'listforA' which has a bunch of objects named A, which I retrieve from a CDO (SQL) query.
next, I do a ...getListForA().removeAll(List<A>) which throws this exception below.

So apparently this is not supported, what would be the appropriate use case to delete objects obtained from a query? Should I create a query which deletes instead?

thx Christophe
