Hi, i have this code:

                                <*a4j:region*>

<*h:selectBooleanCheckbox*value="#{subtipo.seleccionado}"  id="checks"
                                        disabled="#{VDBean.modoEdicion ==
false}" onchange="call some javascript code" >

                                        <*a4j:support* event="onchange"
status="statustablaSubtipoVisita"

actionListener="#{VDBean.select}"
                                                     reRender="checks,
tablaActividadesVisita" >
                                                    * <a4j:actionparam
assignTo="#{VDBean.foo}" value="true" id="foo" />*


                                        </a4j:support>
                                    </h:selectBooleanCheckbox>
                                </a4j:region>

In the VDBean I have a String foo variable with the get and set methods but
when access the foo variable in the VDBean (scope: session) select method it
has the initial value "false". Why the actionParam do not set the foo
variable value??

Can anyone help me?

Thanks
