Subject Check/Uncheck items from selectManyCheckbox
Date Fri, 29 Oct 2010 15:07:41 GMT


I'm trying to check/uncheck the selectManyCheckBox items that depends on the user selection.
For example
damage No 1
damage No 2
damage No 3
no damage

if the user checks the "no damage" option, all other checkboxes should be unchecked
if the user checks a different option from "no damage",  the "no damage" option should be

here is the code in the jsp page

<h:selectManyCheckbox id="danos" value="#{MANT15.damage}" 
                        layout="pageDirection" required="true" valueChangeListener="#{MANT15.procesarDanoSeleccionado}"
                    <f:selectItems value="#{MANT15.damages}"/>

Here is the code in the backing bean

public void procesarDanoSeleccionado(ValueChangeEvent event) {
        HtmlSelectManyCheckbox listaCheckDanos = (HtmlSelectManyCheckbox) event.getComponent().findComponent("danos");
        lista = new ArrayList();
        lista = (ArrayList) listaCheckDanos.getValue();        

the attribute "lista" has the selected values but I don't know how to access to the checkboxes
of each item

Any idea?

Thanks for your time
