I use OpenScales to show a WMS layer and it is strange that when zoom in/out sometimes OpenScales show tiles in cache, so Multi-resolution tiles showed in the layer. When paning the layer, incorrect tiles will disappear. How can I fix this? Thanks!!!

You can force OpenScales to force a refresh using

private function refresh():void{
  var date: new Date();

Source: Layers>WMS 1.3.0
