Prati,
I'm not sure what you mean.
Here's a couple of lines of code implementing what I described:
if(currentSelection != null){
// you should remove existing behaviours on
// currentSelection here or,
// use an AtrributeModifier added, just once, to all your
// labels with a model that has logic
// checking against currentSelection to
// calculate the correct value for your "style" attribute
currentSelection.add(new SimpleAttributeModifier("style", ""));
target.addComponent(
}
currentSelection = contacteLabel;
Just declare "Component currentSelection;" in your RefreshingView.
