Sorry I meant of course: ContainerObj1's children property is a sorted ArrayCollection (although I tried that removing sort has no effect on this issue). If I scroll the ADG so that ChildContainerObj1 and it's children are not visible and programmatically add new ChildContainerObj4 (it has it's own children too!) by calling
ContainerObj.children.addItem(ChildContainerObj4 ); Then the error occurs. It seems to occur quite randomly when adding or removing nodes depending how nodes are opened and ADG scrolled.
