you need to make your models pull, no need for all this fancy event
listenting
class mypage extends webpage {
private boolean green=false;
public mypage() {
add(new link("gogreen") { onclick() { green=true; }});
add(new panel("p1").add(new attributemodifier("class",true,new
greenmodel()));
add(new panel("p2").add(new attributemodifier("class",true,new
greenmodel()));
...
}
private class greenmodel extends abstractreadonlymodel {
object getobject() { return (green)?"green":""; }
}
