After calling PasteFromClipboard, it selects all of the newly inserted top-level objects, and then calls RaiseClipboardPasted. This method does nothing if CanInsertObjects is false. All the actions occur within a transaction. The selection is built between SelectionStarting and SelectionFinished events.

All of the pasted objects will be copied by deserializing them. If any of the objects, or any of the objects that they refer to, are not (de-)serializable, there will be a serialization exception, and the paste might fail. PasteFromClipboard will log any exceptions to any trace listeners. The User Guide discusses serialization and deserialization in more detail.
