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

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

Answer 1

要么获得你正在使用的Faces API实现的新版本（支持泛型的实现），要么在函数开始之前放置@SuppressWarnings("unchecked") （就在public或private之前）。

Answer 2

Add an annotation to suppress the warning if the JSF API forces the use of unchecked casting:

@SuppressWarnings(value = "unchecked")
