> An exception "Collection was modified; enumeration operation may not execute." is thrown while performing a cascaded delete. During the delete I removed the corresponding entity from it's collection (from an interceptor)
> It quickly fixed my problem at Cascade.CascadeCollectionElements(...)
> I replaced:
>                 foreach (object o in action.GetCascadableChildrenIterator(eventSource, collectionType, child))
>                      CascadeProperty(o, elemType, style, anything, isCascadeDeleteEnabled);
> by:
>                 ArrayList list = new ArrayList(); //JS
>                 foreach (object o in action.GetCascadableChildrenIterator(eventSource, collectionType, child))
>                     list.Add(o);
>                 foreach (object o in list)
>                     CascadeProperty(o, elemType, style, anything, isCascadeDeleteEnabled);
