Hello,

I'm developing a plugin with a similar behaviour like the XRef object. And now I have to set some flags so that the linked objects are also save again drag and drop, removing and modifying.
You know, the objects in a XRef objects are protected

Which flags I have to set? Or is it more than flags ?
