[paulwilhelm]

Hello,
hiding unused lanes and rebuilding the timline will hide the lanes but the events too.
kind regards paul

We see the problem and will update here when we have it fixed.

We've made a fix for this (a case where we were not taking your custom laneNameField into account) - you can retest with a build dated May 5 or later.

Note that we also made some optimisations, and added setHideUnusedLanes() - you should call that instead of rebuild(), which is much less efficient - we'll update our Timeline Filtering example to show the new technique as well.

Bug is fixed, but
setHideUnusedLanes()
not implemented.
