I'm having some troubles with relationship types which I've never seen before in my setup for the provenance researchers from Vienna.
I put a dump to test this out on antwerp in /home/stefan/provenienz_18_jan.sql. You can log in with stefan/stefan.
a) If you edit an existing relationship type without specifying a hierarchy location, the parent_id is set to 0 after the save which essentially means that the rel type will not appear in the hierarchy browser anymore. Also, the table_num is set to 0 which is even worse, I guess.
b) The relationship bundles do weird stuff with the type restrictions and I guess this might be related to a). Have a look at the rel type
It says Provenienzmerkmale <-> Provenienzmerkmale (objects_x_objects), right? Now try
This is a "Trägerobjekt" (different object type). Try relating something in the bottom "related objects" bundle. This one is restricted to only display "Provenienzmerkmale" (the bundles have meaningful names in German). And there it is: "ist physisch verbunden mit". Weird.
