Hi. I have a nested list that shows on a button click.

I set its size this way:

Code:
width: Ext.Element.getViewportWidth()*0.75,
          height: Ext.Element.getViewportHeight()*0.9,
Now, if I start the application with my mobile in vertical orientation and i change orientation the nestedlist size won't change. I've tried with "onorientationchange:" but had no succes. Can anyone help with that? thanks

EDIT: Finally i've been able with:
Code:
                orientationchange: function(nestedList,  orientation, width, height){
                    if(orientation=="landscape"){
                        nestedList.setWidth(Ext.Element.getViewportWidth()*0.9);
                        nestedList.setHeight(Ext.Element.getViewportHeight()*0.8);
                    }else if (orientation=="portrait"){
                        nestedList.setWidth(Ext.Element.getViewportWidth()*0.75);
                        nestedList.setHeight(Ext.Element.getViewportHeight()*0.95);
                    }                   
                }
