[platform-dev] correct way to save a model-fragment to later load it aga

[Christoph Läubrich <laeubi@xxxxxxxxxxxxxx>]

I'm currently play around with some advanced e4 model topics and came 
across the "Saving and restoring a perspective of the application 
model"[1] but found some issues:

the code mentioned that
> You must clone the perspective as snippet,
> otherwise the running application would break

Is this still the case? I noticed that when I clone the snippet all 
references for placeholders are lost and loading the perspective fails 
with a lots of "invalid reference" errors.

If I just safe the perspective fragment it produces me an output with 
references (but hard file reference ids) and I could load it but certain 
elements are missing e.g. if I minimize a partstack it is not available 
anymore and for example the editor area (even though the ref is in the 
XMI) is missing.

SO question is, is there something "modern" to safe a part of the model 
in a way that later can be restored without any problems of missing 
references?
