v15 - Import with [X] Strip GUIDs - how far does it go?

[Paolo F Cantoni]

In the past (pre v15) we used to export packages and then re-import with [X] Strip GUIDs as a mechanism to change the abstraction level (using the "Code as Design" paradigm).

If the items in the package had our "Neighborhood" Diagrams as their composite diagrams, they also had a tag with a RefGuid pointing back to the diagram involved.  When the items were p[reviously imported, these RefGUIDs were NOT updated and for the imported package would point back to the original diagram in the original package.  We had to run some direct SQL to fix this up.  No biggy, but still until we did, bedlam could ensue as more than one item tried to update the same diagram

Yesterday  I went through the same export/import process and discovered that the RefGuids had been "fixed" already!  Has anybody else seen this?  It's possible that I made a mistake in my process, but before I tried to run the "Fixer", I ran a query to see how many items were affected and the query said none.  Randomly checking a few items seemed to confirm this!

Can a Sparxian, confirm or deny my observation?

TIA,
Paolo
