Hi,
My model is displayed in a TreeView contained in a MasterBlock.
I would like to record the current Selection to be able to restore it
next time the App is run.

I see the normal serialization uses the pattern:
"#//@node.No/@node.No/@leaf".
The meaning is obvious.
I could use the same notation to save the current Selction to an
IMemento instance.
Is there an (user accessible) API to convert such a notation to EObject
and viceversa? I didn't find it, but there must be something somewhere ;)

TiA
Mauro

Mauro,

EcoreUtil.getURI and ResourceSet.getEObject do that work.
