ungrouping error
If you copy a group of objects to another layer in InDesign, and then ungroup it, those objects disappear. But what actually happens is this: take the group on layer 1, copy it to layer 2, ungroup it. They will disappear from layer 2 and appear on layer 1 UNDER the group object on the original layer 1. And you can turn off the visibility of layer 1 or even lock it completely before ungrouping the objects on layer 2, but what will happen is that the objects will be moved to layer 1 from layer 2 and hidden under the original group of objects.
