Copy and Paste Issue

I am having an issue with copy and paste. If I use the copy selection from the diagram and then delete the original object, when I try to paste the copied object I get a null pointer exception. When I look at the debugger sure enough, the children of the container node is empty after I delete the original item from the diagram.

Code
Select All
                copyData = currentDiagram.CopySelection(true);


And then I read that data on paste.

Copy -> Delete -> Paste worked for me both with containers and child nodes. Could you elaborate on what kind of objects are you copying and in what context?

We have a Container node that contains a shape node and a text block. What I noticed is that the container node is OK but the children are missing if I delete the original object.

That works for me. Are you doing anything special when the container is deleted, e.g. from a NodeDeleted handler? Could you also try the CopyToClipboard and PasteFromClipboard methods? they should not depend on the presence of the original items at all.
