rich:pickList problem with context var

[fjtorres]

Hi all,

I have a problem with my <rich:pickList> I can't submit the items. When executing the application and click in submit button i got the following error.

Caused by: java.lang.IllegalArgumentException: ValueBinding for UISelectMany must be of type List or Array

My picklist code:

...

<rich:pickList id="listaTiposCargo" value="#{tiposSeleccionados}"

     copyAllControlLabel="#{messages['app.comun.pickList.copyAllControlLabel']}" copyAllTitle="#{messages['app.comun.pickList.copyAllControlLabel.titulo']}"

     copyControlLabel="#{messages['app.comun.pickList.copyControlLabel']}" copyTitle="#{messages['app.comun.pickList.copyControlLabel.titulo']}"

     removeAllControlLabel="#{messages['app.comun.pickList.removeAllControlLabel']}" removeAllTitle="#{messages['app.comun.pickList.removeAllControlLabel.titulo']}"

     removeControlLabel="#{messages['app.comun.pickList.removeControlLabel']}" removeTitle="#{messages['app.comun.pickList.removeControlLabel.titulo']}"

     targetListWidth="305" sourceListWidth="305" required="true"  >

     <s:selectItems value="#{tipos}" var="tipo" label="#{tipo.descripcion}"/>

     <f:converter converterId="tipoConverter"/>

</rich:pickList>

..

My context var, in conversation component:

@Name("myController")
@Scope(ScopeType.CONVERSATION)
@Conversational
public class MyControllerImpl extends BaseControllerImpl implements
        MyController
...
// Source for the pickList
@In(required = false, value = "tipos")
@Out(required = false, value = "tipos")
private List<Tipo> listaTipos;

// Target of the picklist
@In(required = false, value = "tiposSeleccionados")
@Out(required = false, value = "tiposSeleccionados")
private List<Tipo> listaTiposSeleccionados;

.....

I don't know what occurs, in other page i have other pickList but not with context var and it's working properly.

My project uses:

Richfaces 3.3.3.Final

Seam 2.2.0.GA

Thanks and regards.
