For several projects we've run into the issue that navigation items don't get a active class (did work in Mendix 4, but nog in Mx5).
That means that navigation is useless for every project that has a different styling of active navigation items.
I already filed a ticket / feature request for this, but in the mean time I'm curious if there are some work around. Also I would like to know if anyone else experienced this as an issue, because I can back-up my ticket with this thread (to get more priority ;)).
