Handlers list

[Kralg]

Hello,

I noticed one funny thing. If there is a list of handlers and if there is no handler named with a single name e.g."Handler" then the list of Applications (Handlers list) in Profile edit does not populate, but if I add handler with the name e.g. "Handler" then it appears again.

The list without a single word Handler: No populated list in Profile:

The populated list in Profile with a single word "Handler"

Hello. I have some troubles reproducing this. What exactly did you have in your Handlers list to get the erroneous handling?

I tried it today but was also unable to do it, I completely changed the lists from that time. However, the problem could come from different case. When there is a handler which is assigned to a profile and I delete this handler, then the list is not populated in the Profile edit window of which that deleted handler was used. In some cases it is good, as in this circumstances person can not change the handler of that Profile but in the Profile list it is possible to see what was the name of that last handler used. Maybe there could be some kind of notification before delete of the Handler (that this handler is being used in this profile and connector) or in Profile edit window that the assigned Handler was deleted and the name was..

P.s.: And right now I am able to have the Applications (Handlers) list populated again if I recreate a handler with the same name that was deleted.

Oh, yes, thats a known issue (#324), which is not easy to fix.

I had troubles in making the Thingsboard communication over mqtt. And for quit a while I was unable to make it to run on daemon lorawan server while by manualy started server from different location it was working. I was getting these errors on the daemon server: Oct 09 09:42:09 gateway lorawan-server[1252]: 09:42:09.168 [debug] Reconnecting Oct 09 09:42:09 gateway lorawan-server[1252]: 09:42:09.171 [warning] ClientId is NULL!

But my main target was mqtt with Conn_4th connector. Once I recreated the Handler1 I noticed that the Conn_4th authentication part is empty, however I was pretty certain that it was filled before, then i filled it in and it started working. This sounds confusing and I am wondering if this could somehow be related to the missing Handler1 or not, because yesterday I was recreating Conn_4th (for thingsboard) and it handler over and over again to make it work and did not care about other connectors and handlers.
