Hi,
I'm trying to shake a window, but got error mess in console. My code:
var win = new qx.ui.window.Window ("Login");
win.setLayout (new qx.ui.layout.Grow);
win.add (view);
this.effect = new qx.fx.effect.combination.Shake (
win.getContainerElement ().getDomElement ());
return win;
Where view is a GroupBox instance (from demobrowser/animation/login).
