Problem binding boolean value to checkbox

[snichele]

Hello everyone.

I have a really annonying problem with a somewhat evident thing : setting a boolean value of a command object from a checkbox.
Here is my code.

Business Class

public class DemandeDeCatalogue {
    private boolean optin;
    private Address address = new Address();
    private String codeGestion = DemandeDeCatalogue.UNSPECIFIED_CATALOGUE;
    public static final String UNSPECIFIED_CATALOGUE = "-1";
...(snip)

(note : getters and setters are ok, of course... )

Controller Class

public class CatalogueDemandeFormController extends BaseFormController {  
    (snip...)
    public CatalogueDemandeFormController() {
        setCommandClass(DemandeDeCatalogue.class);
    }
    (snip...)
    protected void initBinder(HttpServletRequest request,
            ServletRequestDataBinder binder) {
        
        binder.registerCustomEditor(
                null,
                "address.dateNaissance",
                 new CustomDateEditor(AddressValidator.dateFormat, true)
        );
        
        binder.registerCustomEditor(
                null,
                "optin",
                 new CustomBooleanEditor(true)
        );
            (snip...)
    }

and
jsp form extract

<form action="demandeCatalogue.html" method="post" name="demandeCatalogueForm">
        <spring&#58;bind path="command.address.civility">
        <p><label for="<c&#58;out value="$&#123;status.expression&#125;" />">Civilité</label>

            <input type='radio' name='<c&#58;out value="$&#123;status.expression&#125;" />' value="4" <c&#58;if test="$&#123;status.value == 4&#125;">checked="checked"</c&#58;if> />Société
        </p>
        </spring&#58;bind>

        <spring&#58;bind path="command.address.dateNaissance">
        <p><label for="<c&#58;out value="$&#123;status.expression&#125;" />">Date de naissance</label>
            <input type="text" 
                name="<c&#58;out value="$&#123;status.expression&#125;" />"
                id="<c&#58;out value="$&#123;status.expression&#125;" />"
                value="<c&#58;out value="$&#123;status.value&#125;" />"
                size="10" maxlength="10" />
        </p>
        </spring&#58;bind>

        <spring&#58;bind path="command.address.diversAdresse">
        <p><label for="<c&#58;out value="$&#123;status.expression&#125;" />">Divers adresse</label>
            <input type="text" 
                name="<c&#58;out value="$&#123;status.expression&#125;" />"
                id="<c&#58;out value="$&#123;status.expression&#125;" />"
                value="<c&#58;out value="$&#123;status.value&#125;" />"
                size="30" maxlength="30" />
        </p>
        </spring&#58;bind>


            <spring&#58;bind path="command.optin">
            <input type="checkbox" name="<c&#58;out value="$&#123;status.expression&#125;" />" id="<c&#58;out value="$&#123;status.expression&#125;" />" 
            <c&#58;if test="$&#123;status.value == 'on'&#125;">checked="checked"</c&#58;if> />
            </spring&#58;bind>

            <input type="submit" id="save" name="save" alt="Enregistrer" title="Envoyer" />            

</form>

I have and AddressValidator class that perform checks on the nested Address class included in the DemandeDeCatalogue class.

Fact is that, after some tests, that EVERYTHING works fine (validating nested Address fields was easy as a breathe ! ) BUT the 'optin' fields fails miserably !
I get a

Failed to convert property value of type [java.lang.String] to required type [boolean] for property 'optin'; nested exception is java.lang.IllegalArgumentException: Invalid boolean value [on]

when I check the box.

I'm totally helpless... everything run smoothly without any problem, even the Date field (providing I set the CustomDateEditor), but it obviously seems to ignore my BooleanCustomEditor...

Any help would be GREATLY appreciated !

Thanks,

sne.
