Hi,

I'm building a Listview scrollable with multiple columns but having fixed header. From what I've read I should use the property "headerPositionning" of the Listview set to OverlayHeader. But I found that if I set the listview height with a percentage of the windows height, this is freezing the UI (maybe a forever loop or deadlock I don't know but I can no longer move or resize the window).

See in attachment for code to reproduce the problem.
