How get selected valuess in backing bean for <h:SelectManyLi

[xlugo2010]

I use RF 3.1.3 and Myfaces 1.1.4

This code is working :
<f:view>
<h:form>
<a4j:region id ="region2">
<h:selectOneMenu value="#{cursosUsuario.idRegion }" id="cursos">
<f:selectItems value="#{cursosUsuario.regiones}" />
</h:selectOneMenu>
<a4j:commandButton reRender="datos" value="consultar" actionListener="#{cursosUsuario.generaReporte}" />
</a4j:region>
<h:outputText value="#{cursosUsuario.showSelectedRoles}" id="datos" />
</h:form>
</f:view>

Bean:
.................

private String idRegion; //get and set
private String showSelectedRoles;

public void generaReporte(ActionEvent event){

ValueHolder uic = (ValueHolder) event.getComponent().findComponent("cursos");
this.showSelectedRoles = (String) uic.getValue();
------------------------------------------------------------------------------------------------------
But when i use multiple selec values
<f:view>
<h:form>
<a4j:region id ="region2">
<h:selectManyListbox value="#{cursosUsuario.selectedRoles}" id="cursos">
<f:selectItems value="#{cursosUsuario.regiones}" />
</h:selectManyListbox>
<a4j:commandButton reRender="datos" value="consultar" actionListener="#{cursosUsuario.generaReporte}" />
</a4j:region>
<h:outputText value="#{cursosUsuario.showSelectedRoles}" id="datos" />
</h:form>
</f:view>

Bean:

private String[] selectedRoles; //get an set

public void generaReporte(ActionEvent event){
-----------------------------------------------------------------
I Don know how get the multiple selected values:
ValueHolder uic = (ValueHolder) event.getComponent().findComponent("cursos");
(?) uic.getValue();???? Array Collection???
---------------------------------------------------------------

Your custom logic to get the value from component isn't need at all. In the moment when actionListener called - values already updated in the model.
