Setting up dynamic_reconfigure with groups results in error from rqt_reconfigure:

Here is the error message:

It doesn't matter, if I only specify the groups name or additional the type (collapse, hide) or the state (true, false).

I tested on groovy and hydro with the same result. I'm using the c++ API and Ubuntu x64.

Groups support is not done. Needs to be completed.

Another report from answers. I'll still keep from assigning myself unless I start working.

@cottsay May be you can look into this a some point (I know it might need a lot of work)...
