Given containers for a generic couple of values, e.g. double (pair), tripple, ...

public class Pair<T1, T2> {

    private T1 _value1;
    private T2 _value2;

    [getters and setters]
}

public class Tripple <T1, T2, T3>{...}

Now, these structures are used within a list and shall be accessed from a JSF page

	<h:dataTable value="#{myBean.myList}" var="var">

"var." -> NetBeans offer code completion (value1, value2, value3)

"var.value1." -> Error. Unlike in Java editor, NetBeans does not offer code completion.
