The link was pointing to the wrong place - going to ODB instead of staying on the same page.
> > When using a slowcontrol frontend which operates a device using the multi class
> > driver the current midas version (ec3225902d6) has the following issue:
> > There is a row labeled with: All Input Output
> 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

> 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.

> > Error: cannot find key LS336/Variables/Input
> Looks like the /Equipment part is missing from the ODB path...
