Question

I am getting warning

warning: [unchecked] unchecked call to add(E) as a member of the 
raw type java.util.List
    [javac]      listbox.getChildren().add(listaMenu); 

where listaMenu is declared as

UISelectItems listaMenu = new UISelectItems();

and listbox is declared as

HtmlSelectOneListbox listbox = new HtmlSelectOneListbox();

How can I get rid of this warning message when I compile using ant build tasks?

Thanks

Either get a new version of the Faces API implementation you’re using (one that supports generics), or put @SuppressWarnings("unchecked") just before the start of the function (right before where public or private would go).
