1. adding objects to surface
surfaceGalleriesDisplay.addChild(grpFrame); //rect that used as a frame for
an image - added object is a GeometryGroup
surfaceGalleriesDisplay.addChild(im); //Flex Image
surfaceGalleriesDisplay.addChild(grpThump); //another rect used as mask for
the image               
                    surfaceGalleriesDisplay.addChild(detailsCanvas);//a flex canvas object
over the image

2.hook to the canvas (details canvas) ROLL_OUT event
details.addEventListener(MouseEvent.ROLL_OUT,hideItemDetails);

3.event handler will change the image frame (rect inside a geometryGroup)
stroke
var stroke:SolidStroke = isOver ? strokeWhite : strokeBlack;

var frame:RoundedRectangle =    
grpItem.frame.geometryCollection.getItemAt(0) as RoundedRectangle;
frame.stroke = stroke; //THE PROBLEM

the actual stroke reference is updated on the object ,
but the view doesn't change event after a call to invalidate

the only way to resolve this
is to change the property using or something like that
setTimeout(itemSelectionEffect,1);
