Knowing the value of a FilterOptions selected in a column

[josejim]

I need to filter data from multiple FilterOptions depending on the selection made. How I can know what value they selected?

I need that when a user selects a school to display only the sites that belong to that school.

Code: Select all

<p:dataTable value="#{Cuota.ofertasAcademicas}"
                             var="oferta"
                             paginator="true" rows="10"  
                             selection="#{Cuota.ofertasSeleccionadas}" >

<p:column headerText="School"
                              filterBy="#{oferta.sede.centroEducativo}"
                              filterOptions="#{Cuota.centroEducativoSelectItems}"
                              binding="#{Cuota.centroEducativoElegido}">
                        <h:outputText value="#{oferta.sede.centroEducativo}" />
                    </p:column>

                    <p:column headerText="Site"
                              filterBy="#{oferta.sede}"
                              filterOptions="#{Cuota.sedeSelectItems}" >
                        <h:outputText value="#{oferta.sede}" />
                    </p:column>

 </p:dataTable>
