Continuing the discussion from openHAB 3.4 Release discussion:
Update 3.1->3.4 (RPi3+), loss of semantic model
After successfull update I realized that I lost nearly the complete semantic model. Only first level House is remaining, no more floors rooms, etc.
After first depressive phase I startet to rebuild but can’t add any sublevel any sublevel (Name: 1EG, Label 1EG, type:location, category:groundfloor). in the upper left corner there pops up a message “Item not created:Bad request”. I found that I don’t have to start with a number. Using as name “EG” instead of “1EG” works. Why?
Info to the field is “alpanumeric and underscores only” which also includes “1EG” or am I wrong?
In the old version I used “1EG” (Probably I remember wrong, see answers below). Could this be a reason for the loss? and furthermore why is field “type” preoccupied with group and not with location when I add anew location?
Thanks in advance for any respond
