CloneBeforeWrite

Some clarification 
on the use of CloneBeforeWrite.

 

In the Primmer it 
looks like the CloneBeforeWrite is only valid on offered handles. Is this true? 
If you look at 6.1.2 Portlet Lifecycle (figure 5) it shows what seems to be only 
the portlet management interface can clone a clone. Can consumers call 
CloneBeforeWrite on already cloned handles? If so should a new handle be 
returned or is there any circumstance that the same handle could be 
returned. 

 

I have seen a number 
different implementations treating the cloning in different ways. Is there a 
consensus on how cloning should occur.

 

Thanks
