Hi, sorry for the late reply. The problem exists with the itemrenderer. It apperars a scrollbar at right side. only when touching the top or the bottom of the scrollbar it is possible to scroll.

Hi,

Please share working sample project in zip file via any content sharing tool as the code shared by you isn’t complete and we are failing to compile it or log a bug at https://tracker.adobe.com/ and upload your working project there.

Thanks,

Hi, this is a very complex code and I need to send the whole app for this. The itemrenderer receives the informations from an xml file on our server. Please understand, that I can´t send this code. Fact is that the <s:List itemRenderer="com.myapp.ActivitiesRenderer" /> is only scrolling if you touch the scrollbar. If you touch the screen the List is not scrolling anymore since Air 31.

With AIR 30 the scrollbar did not appear and the behaviour was normal. I hope you may fix this, bcs it is a bug.
