spring mvc - JSP int values are casted to bool -

i'm working on project in jsp , have problem generated html.

generated html: "1" transformed "oui" (yes in french) , "0" "non" (no in french)

<select id="privilegesrole" name="privileges" multiple="multiple">     <option value="5" selected="selected">role 1</option>     <option value="4" selected="selected">role 2</option>     <option value="oui" selected="selected">role 3</option>     <option value="6" selected="selected">role 4</option>     <option value="2" selected="selected">role 5</option>     <option value="non" selected="selected">role 6</option>     <option value="3" selected="selected">role 7</option> </select> 

my jsp code:

<form:select path="privileges" multiple="true" id="privilegesrole">     <form:options itemlabel="libelle" itemvalue="id" items="${role.privileges}" /> </form:select> 

controller: in controller values good

roleadministration role = findby....(); model.addattribute("role", role); 

thank in advance help

edit: have booleanformatter.java not see used

import org.springframework.format.formatter; import org.springframework.stereotype.component;  @component public class booleanformatter implements formatter<boolean> {     private string truelabel = utilmessages.getinstance().getstring("common.oui");     private string falselabel = utilmessages.getinstance().getstring("common.non");     @override    public string print(boolean arg0, locale arg1) {        return arg0 ? truelabel : falselabel;    }     @override    public boolean parse(string arg0, locale arg1) throws parseexception {        if (boolean.true.tostring().equals(arg0))            return true;        else if (boolean.false.tostring().equals(arg0)) {            return false;        } else if (truelabel.equals(arg0))            return true;        else if (falselabel.equals(arg0)) {            return false;        }        throw new parseexception(arg0, 0);    } } 

we have changed jsp code to:

<form:select id="privilegesrole" path="privileges" multiple="true" >     <c:foreach items="${role.privileges}" var="currprivilegeselect">         <option value="<c:out value="${currprivilegeselect.id}"/>"                  title="<c:out value="${currprivilegeselect.description}"/>">                  <c:out value="${currprivilegeselect.libelle}"/> </option>     </c:foreach> </form:select> 

and works, don't know why. if have explication happy read :)

check privileges object inside roleadministration, field id, according spring formatter documentation can associate field either annotation formatted or implement custom format annotation. in case can like

@formatted(booleanformatter.class) or @booleanformatted

both on top of field id inside privileges object.
