You may want to try the control from Jenia. It is made to handle radio
and check boxes in a data table.
http://www.jenia.org/
Look under the dataTools "family"
You can then have something like:
XHTML:
<t:dataTable var="item" value="#{bean.items}">
<t:column>
<jdt:multipleRowsSelector selectionList="#{bean.selectedItems}" />
</t:column>
</t:dataTable>
Java:
@Name("bean")
public class ExampleBean
{
private List<Item> items = new ArrayList<Item>();
private List<Item> selectedItems = new ArrayList<Item>();
public List<Item> getItems() { return items; }
public List<Item> getSelectedItems() { return selectedItems; }
public void setSelectedItems(List<Item> selectedItems)
{ this.selectedItems = selectedItems; }
}

Hello there! We have a team developing a system using JSF in my company. I'm
not a JSF person (I'm involved with Tapestry, but please I'm not here to
compare, judge or anything, just seeking help)
So the team came to me because they're facing a problem.
We have a master-detail form, where we list the items using a dataTable and
we have basic Crud operations as commandLinks.
Our problem is, when the user selects items using the selectBooleanCheckBox
and clicks on the remove button, when we retreive the bounded variable it
does not has the objects with their boolean properties modified hence we can
not change the original list.
I don't know anything about JSF, but I guess this is a simple problem our
developers are facing, if someone care to help me out here:
<h:panelGrid columns="3">
<h:commandButton id="novo"
action="#{manterEvento.novo}"
image="resources/imagens/bt-novo.gif"
onclick="location.href='manterConvite.jsf'"
immediate="true"/>
<h:commandButton id="SalvarEnviar"
image="resources/imagens/bt-salvar-enviar-convite.gif"
action="#{manterEvento.salvarEnviarConvite}"
onclick="submit();" />
<h:commandButton id="ApagarSelecionados"
image="resources/imagens/bt-apagar-selecionados.gif"
action="#{manterEvento.excluir}"
onclick="excluir('form');" immediate="true"/>
</h:panelGrid>
<t:dataTable id="listaEventos"
value="#{manterEvento.listaEventos}"
binding="#{manterEvento.listaUIData}"
var="evento" rows="4" width="100%"
headerClass="cabecalho-tabela"
footerClass="rodape-tabela">
<t:column>
<f:facet name="header">
<t:selectBooleanCheckbox
onclick="selecionarTodos(this, 'form')" />
</f:facet>
<t:selectBooleanCheckbox
value="#{evento.selecionado}"/>
</t:column>
The problem happens when the user clicks on the "ApagarSelecionados"
commandButton, our managed bean:
private EventoService eventoService;
private UsuarioService usuarioService;
private Evento evento;
private List listaEventos;
private UIData listaUIData;
//getters and setters
public String excluir() {
List l = (List)listaUIData.getValue();
eventoService.excluirEventos(l);
return null;
}
problem is that the excluirEventos methods, checks each Evento and see if
selecionado is set to true, case it is, the event is removed from database,
but as I said, no value is being changed from the list.
Best Regards
