Class DanglingReferenceException

All Implemented Interfaces:

public class DanglingReferenceException
extends java.lang.RuntimeException

During a cloneTree call an updated reference was requested for a node that did not get cloned. This happens when a sub-graph is duplicated via cloneTree and has at least one Leaf node that contains a reference to a Node that has no corresponding node in the cloned sub-graph. This results in two Leaf nodes wanting to share access to the same Node.

If dangling references are to be allowed during the cloneTree call, cloneTree should be called with the allowDanglingReferences parameter set to true.
