John,
Metrics -- These are part of "layoutblocks", which is an extension of "blocks". The layout blocks schema is missing the metrics element. I can fix that. The default value is 200 which is not written to the panel xml file.
It took a while but I think I have figured out the "missing" NX data. It is actually there but not accessible. The startup process was creating 2 EntryExit managers. The first one was created at the beginning of startup and was used during the loading of the panel xml file data. This is what allows the NX processes to work. The second one was created at the end of the startup process, but it is empty. That is why selecting "Tools >> Entry Exit..." is always blank after the JMRI startup. I think I have a fix for this issue. I need to finish testing to make sure I don't break something else.
I tested stacking on my sample NX config (referenced in the previous message), and it worked as expected. The problems you are seeing may be caused by the "2 managers" issue.
The "double cross-over" block routing problem also affects signal mast logic. I just delete the impossible signal mast logic.
When Path routing starts messing up, usually due to changes to the track plan, I go to Tools >> Blocks >> Paths >> Delete Paths... After a save and restart, the paths are automatically rebuilt during startup.
There is no way I would try to change them manually. If you want to try and understand block routing, the following URL might help:
