This is the "slow control" page you enter by clicking on the equipment name
on the midas status page, yes?

There is some kid of logic behind that link that send one either to the ODB page
for /Eq/XXX/Variables or to the "slow control" page that displays
/Eq/XXX/Variables in a table.

I just tried it and I cannot get to this page in my test experiment, so it will take
a few minutes for me to reproduce your problem. But I think I know where the breakage
is - with the new URL scheme, the links for selecting which variable to show either
was not converted to the new URL scheme or there is a bug and it send us to the wrong place.

I do not remember testing that code, so I will take a look at it definitely.

Looks like the /Equipment part is missing from the ODB path...

K.O.
