I use designer from my windows laptop, with openhab deployed on a linux box. I use samba / windows share to access the configuration folder, the .items and other files etc open / edit just fine however items are not populated in the items window.
in case you have changed any samba setting while still or auto-connected to the Linux share via Windows explorer, open a dos prompt and type:
net use \<linux_host_name> /delete
… and log into the Linux share again
I had a similar problem the other day with designer on Windows, and it was suggested to delete in re-install the drive:openhab directory. This fixed the problem.
he designer creates a few file and directories after its first start, and in case you open the designer twice or force-kill it one or more files get corrupt and cause all sorts of weird errors.
Hate to phrase it this way, but you really really don’t want auto complete on . . I’ve had times when it takes ten seconds for the auto complete list to populate because there were so many options. Doing this all the time would drop designer’s usability dramatically.
