            </f:facet>
            <p:outputPanel 
                rendered="#{(column.header eq 'CHECKVALUE1') or (column.header eq 'CHECKVALUE2')}" >
                <p:selectBooleanCheckbox value="#{car.checkValue}"  id="checkboxId">
                </p:selectBooleanCheckbox>
            </p:outputPanel>
            <p:outputPanel 
                rendered="#{(column.header ne 'CHECKVALUE1') and (column.header ne 'CHECKVALUE2')}" >
                #{car[column.property]}
            </p:outputPanel>
        </p:columns>
    </p:dataTable>
</h:form>

and i want to submit checkbox values to bean with ajax how could i do that ?? I tried to write something like:

<p:selectBooleanCheckbox value="#{car.checkValue}"  id="checkboxId">
    <p:ajax update="@form"/>
</p:selectBooleanCheckbox>

But the value doesnt set to bean..

Answer 1

<p:selectBooleanCheckbox value="#{car.checkValue}"  id="checkboxId">
        <p:ajax update=":form" listener="#{car.addMessage}"/>  
</p:selectBooleanCheckbox>
