Open a weighted service in Dashboard (HTTP Services tab).

Hello,

I use your configuration and I don't reproduce:

[strarsis]

@ldez: You have to open/view the weighted service (test1-api@file).

Side note: It would be nice if one can just click on the listed services that are listed in another service and then go to that service instead. Currently one has to go back to services list first, then select the service that has been previously listed for the other service.

Ok I reproduce:
