…o#6077) When an AppliedToGroup or AddressGroup is derived from a ClusterGroup or Group, we used the existence of the source Group in the internal group storage as the indicator of the type of AppliedToGroup or AddressGroup. After the source Group is deleted, the AppliedToGroup or AddressGroup was considered as a Group with its own selector mistakenly. Accessing its selector would panic due to nil pointer dereference. This patch makes the type of AppliedToGroup and AddressGroup more explicit by adding a field "SourceGroup" to indicate it. If the source Group can't be found in the storage, we just return nil to indicate the Group selects nothing at the moment. Signed-off-by: Quan Tian <qtian@vmware.com>
