Hi!
I have sam eproblem getAttribute give object type Map and I think that you cant
use ArrayList conversion, but I dont now. I try this:
Hello everybody!
I have a problem in Homework in Lab-4108. I just cant find how to display
attribute, beacause for UIComponent comp, comp.getAttributes() return
Map<String,Object> m object, so I try funcion toString(), it just wrote map to
function getAttributeMethod, I try value() funcion Glass Fish reported error
message and my NetBean IDE was blocked , I just don't know what to do. I try
with
for (Map.Entry<String, Object> e : m.entrySet()){
System.out.println(e.getKey() + ": " + e.getValue());
}
and my NetBean IDE was blocked.
I just don' know what to do?
Do we have to do this homework, or only that is numbered with # in the topics?
But nobody answer to me, why, I don't know ?

Hi! I have a problem with the use getAttributes() method of the
UIComponent class.
Code of the method:
public void printComponentTree2(UIComponent comp) {
printComponentInfo(comp);
// Get child components
List complist = (ArrayList)(comp.getAttributes().values());
if (complist.size() > 0) {
indent++;
}
Iterator<UIComponent> it= complist.iterator();
while(it.hasNext()){
printComponentTree(it.next());
}
}
The problem is the cast.
In console, the error:
threw exception: java.lang.ClassCastException: java.util.HashMap
$Values cannot be cast to java.util.ArrayList java.util.HashMap$Values
cannot be cast to java.util.ArrayList.....
.........................
I not find way of the solution at the problem for display of the
attributtes.
Regards.
