datatable + Instant row selection

[juanjo68]

Hello, I´m using datatable in a case similar like your example in

http://www.primefaces.org:8080/prime-sh ... onAjax.jsf

My problem is when i select an item, it work fine, but, in the second and next selections, the first item i selected is shown again in the update panel.

Let me show what i do.

In the client side:

Code: Select all

                        <p:dataTable emptyMessage="Ningún registro encontrado" firstPageLinkLabel="Primero" id="dataTable1" lastPageLinkLabel="Último"
                            loadingMessage="Cargando datos" nextPageLinkLabel="Siguiente" paginator="true" previousPageLinkLabel="Anterior"
                            rows="15" selection="#{RequestBean1.minaSeleccionada}" selectionMode="single"
                            style="left: 744px; top: 114px; position: absolute; width: 400px; z-indez: 10;" update="display" value="#{SessionBean1.arrayMinas}"
                            var="currentRow" width="456"
                            onselectComplete="minaDialog.show()"
                            >
                            <p:column id="column1">
                                <h:outputText id="outputText1" value="#{currentRow['seleccion']}"/>
                                <f:facet name="header">
                                    <h:outputText id="outputText2" value="S"/>
                                </f:facet>
                            </p:column>
                            <p:column id="column2">
                                <h:outputText id="outputText3" value="#{currentRow['provincia']}"/>
                                <f:facet name="header">
                                    <h:outputText id="outputText4" value="Provincia"/>
                                </f:facet>
                            </p:column>
                            <p:column id="column3">
                                <h:outputText id="outputText5" value="#{currentRow['numeroRegistro']}"/>
                                <f:facet name="header">
                                    <h:outputText id="outputText6" value="Nº de Registro"/>
                                </f:facet>
                            </p:column>
                            <p:column id="column4">
                                <h:outputText id="outputText11" value="#{currentRow['denominacion']}"/>
                                <f:facet name="header">
                                    <h:outputText id="outputText12" value="Denominacion"/>
                                </f:facet>
                            </p:column>
                        </p:dataTable>

                        <p:dialog header="Detalle Explotación" widgetVar="minaDialog"
                       modal="true" fixedCenter="true" draggable="false" width="250px">
                        <h:panelGrid columns="2" id="display" style="height: 96px; left: 792px; top: 0px; position: absolute; width: 400px; z-indez: 10">
                            <h:outputText value="Provincia:"/>
                            <h:outputText style="font-weight:bold" value="#{RequestBean1.minaSeleccionada[0].provincia}"/>
                            <h:outputText value="Nº de Registro:"/>
                            <h:outputText style="font-weight:bold" value="#{RequestBean1.minaSeleccionada[0].numeroRegistro}"/>
                            <h:outputText value="Denominación:"/>
                            <h:outputText style="font-weight:bold" value="#{RequestBean1.minaSeleccionada[0].denominacion}"/>
                        </h:panelGrid>
                        </p:dialog>

In the server side
SessionBean1:

Code: Select all

    private MinaSelec[] ArrayMinas;
    //setters an getters

RequestBean1:

Code: Select all

    private Object[] MinaSeleccionada;
    public void setMinaSeleccionada(Object[] MinaSeleccionada){
        this.MinaSeleccionada=MinaSeleccionada;
    }
    public Object[] getMinaSeleccionada(){
        return this.MinaSeleccionada;
    }

To finish my exposition: I´m using, Jsf1.2, J2EE 1.4, Server Glassfish V2, primefaces 1.0.0.RC

I´m sure i´m doing something worng, can you help me, please

Thank you
Best Regards

Please,
There is nobody who happens to the same thing?

Is it possible that I have not explained well?

When I try to select other rows, always there appears the first row that I selected.


Thanks in advance

J2EE 1.4? You have JDK 1.5 right? Just to make sure.

[juanjo68]

Yes, I've checked my JDK 1.5 and is ok. I´ve reinstalled it back.

I´m still working about the problem, if you have another suggestion, please, tell me.

Thanks.

Hello,

I don't know, but look

Code: Select all

... selection="#{RequestBean1.minaSeleccionada}" selectionMode="single" ...

your selection mode is single, but "selection" attribute references an array. Try to write

Code: Select all

private Object MinaSeleccionada;

and adjust getter / setter.

Best regards.
Oleg.

[juanjo68]

Thanks for your reply, Oleg, but, It seems that the selection property is attached to a Object´s array in the backing bean always, Independently that the selection mode is "single" or "multiple".

Others suggestion will be welcome.

Thanks.

[cagatay.civici]

Can you try with the latest snapshot, new enhancements are added regarding row selection. For single selection now you can use the actual data type and for multiple array of that data type so no more Object[].

Example is updated as well;

http://www.primefaces.org:8080/prime-sh ... onAjax.jsf

You can get the nightly builds from http://www.primefaces.org/downloads.html

[juanjo68]

Hi cagatay, thank you very much for your time. I´ve got the nightly build. I´ve changed the type selection from Object[] to the corresponding data type (MinaSelec in my case) and I´ve changed the value of datatable from Object[] to List<MinaSelec> also. Its works ok, but, unafortunately, only the first time.

It´s so extrange...

[cagatay.civici]

So subsequent selections still select the first one always, the example in online showcase works right? As I see you have two beans with different scopes right? Can you try movign the selection minaselect to the session bean to see if it makes a difference? It doesn't make much sense though, just to try.

[juanjo68]

Yes, of course, the example works all right and, about of scope, I thought the same thing and i moved the Object´s selection to the session scope yesterday and nothing.
I´m suspecting my problem is related with my projects´s libraries. I don´t know, perhaps the JSF 1.1/1.2 Support (jsfcl.jar, appbase.jar,etc.)
