What is the type of "mListeSite"? May be you should use a field in some bean and this field must be String.

[pousino]

Definition of my mListeSite :

... @DataModel

    private List<Site> mListeSite;

    and Site is composed of a int and a string : like

   private int mIdSite;

   private String mLibelleSite;

1) Please ignore my comment about String type.

2) Please remove @DataModel annotation. It should be just List
