recover values rich:dataTable

[rodmen]

Hi,

How can I recover the values that are in a rich:dataTable

Like this

<r:dataTable id="listaDetalleRegion" var="iteraDetReg" value="#{detallePedidoBean.listaDetalleRegion}" width="100%"

onRowMouseOver="this.style.backgroundColor='#ffffff'"

                        onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'">

<f:facet name="header">

<r:columnGroup>

                            <r:column>

                                <h:outputText value="Plaza"/>

                            </r:column>

                            <r:column>

                                <h:outputText id="comisionPorcentaje" value="#{detallePedidoBean.comisionPorcentaje}"/>

                            </r:column>

                            <r:column>

                                <h:outputText id="costoPorcentaje" value="#{detallePedidoBean.costoPorcentaje}"/>

                            </r:column>

                            <r:column>

                                <h:outputText value="Pagina"/>

                            </r:column>

                            <r:column>

                               <h:outputText value="Total Paginas"/>

                            </r:column>

                            <r:column>

                                <h:outputText value="Comentario"/>

                            </r:column>

</r:columnGroup>

</f:facet>

<r:columnGroup style="width: 100px;">

        <r:column width="20%" style="text-align: center;">

    <h:outputText value="#{iteraDetReg.nombreCiudadRegion}"/>

        </r:column>

        <r:column style="text-align: center;">

<h:inputText id="proporcionComisionPlaza" value="#{iteraDetReg.proporcionPorcentajePlaza}" styleClass="inputTextPropPlaza" onkeypress="return isNumberKey(event);" 

onchange="return proporcionComision('#{row}', '#{detallePedidoBean.totalPlazas}')" onkeyup="onlyNumberMaxMin(this.value, this.id);" maxlength="5" required="true">

<f:convertNumber integerOnly="true" maxFractionDigits="2" maxIntegerDigits="3" minFractionDigits="2" minIntegerDigits="0" type="number" />

</h:inputText>

        </r:column>

        <r:column style="text-align: center;">

<h:inputText id="proporcionCostoPlaza" value="#{iteraDetReg.proporcionCostoPorcentajePlaza}" styleClass="inputTextPropCosPlaza" onkeypress="return isNumberKeyDec(event);" 

onchange="return proporcionCosto('#{row}', '#{detallePedidoBean.totalPlazas}')" maxlength="10" required="true">

<f:convertNumber integerOnly="true" maxFractionDigits="2" maxIntegerDigits="7" minFractionDigits="2" minIntegerDigits="0" type="number" />

</h:inputText>

        </r:column>

        <r:column width="10%" style="text-align: center;">

<r:inputNumberSpinner id="numeroPaginaEdicion" value="#{iteraDetReg.numeroPaginaEdicion}" minValue="0" maxValue="#{iteraDetReg.numeroTotalPaginasEdicionRegion}" oninputkeypress="return stopRKey(event);" cycled="true" required="true">

<f:convertNumber integerOnly="true" maxFractionDigits="0" maxIntegerDigits="3" minFractionDigits="0" minIntegerDigits="0" type="number"/>

</r:inputNumberSpinner>

        </r:column>

        <r:column width="10%" style="text-align: center;">

    <r:inputNumberSpinner id="numeroTotalPaginaEdicion" value="#{iteraDetReg.numeroTotalPaginasEdicionRegion}" minValue="0"  maxValue="1000" oninputkeypress="return stopRKey(event);" cycled="true" required="true" onchange="maxValue(this);">

<f:convertNumber integerOnly="true" maxFractionDigits="0" maxIntegerDigits="3" minFractionDigits="0" minIntegerDigits="0" type="number"/>

</r:inputNumberSpinner>

        </r:column>

        <r:column width="20%" style="text-align: justify;">

    <h:inputTextarea id="comentarioRegionPlaza" value="#{iteraDetReg.comentarioRegionPlaza}"/>

        </r:column>

        </r:columnGroup>

</r:dataTable>

I’m trying this way but I can not get it, I need to extract the values.

org.richfaces.component.html.HtmlDataTable listaDetalleRegion = (org.richfaces.component.html.HtmlDataTable)form.findComponent("listaDetalleRegion");

        //DataTable listaDetalleRegion = (DataTable)form.findComponent("listaDetalleRegion");

        try{

        System.out.println("****proporcionCostoPlaza.getChildren() "+listaDetalleRegion.getChildren());

        for(int i=0; i<listaDetalleRegion.getChildren().size(); i++){

        UIComponent columnas = (UIComponent) listaDetalleRegion.getChildren().get(i);

            System.out.println(i+" columnas****---> "+columnas.getChildren());

            System.out.println(" columnas.getChildren().size() "+columnas.getChildren().size());

            for(int j=0; j<columnas.getChildren().size(); j++){

            UIComponent renglones = (UIComponent)columnas.getChildren().get(j);

            System.out.println(i+" - "+j+" renglones****---> "+renglones.getChildren());

            System.out.println(" renglones.getChildren().size() "+renglones.getChildren().size());

            for(int k=0; k<renglones.getChildren().size(); k++){

            UIComponent datos = (UIComponent)renglones.getChildren().get(k);

                System.out.println(i+" - "+j+" - "+k+" datos****---> "+datos.getChildren().toString());

                System.out.println(" datos.getChildren().size() "+datos.getChildren().size());

            }

            }

        }

        }catch(Exception ex){

        System.out.println("## Error: "+ex);

        }

Thank you

How can I recover the values that are in a rich:dataTable

sorry, but i'm not sure that get the point.

[nbelaevski]

Hi,

You can use walk(...) method.

[rodmen]

Hello, what I want to know is… how to recover the value of the field, for example the input text value that is in the dataTable cause I’m trying to recover the whole list and get the value of each element, but instead I’m getting the name of each field.

Thank you.

[nbelaevski]

You can read updated values from "iteraDetReg" - or am I not getting the problem correctly?

[rodmen]

Yes, that’s my problem, and I don’t understand who to use the walk method.

thank you

If your problem is how to get updated values of the input elements in the datatable, then why are you trying to get HtmlDataTable object and try to find values from there ???

You have set the value of inputText to value="#{iteraDetReg.proporcionPorcentajePlaza}" where iteraDetReg is an element of the listaDetalleRegion Collection. This means that after any action, properties of elements of the listaDetalleRegion will update their values by the

new ones -- proporcionPorcentajePlaza will contain the new value of the <h:inputText id="proporcionComisionPlaza"....

So you have to iterate through the listaDetalleRegion Collection (which is the value of your rich:dataTable), and find the updated values of it's elements properties...

[rodmen]

Hello Harut, I try but the detallePedidoBean.listaDetalleRegion is null

I did this...

DetallePedidoBBean detallePedidoBean = (DetallePedidoBBean) request.getAttribute("detallePedidoBean");

listaDetalleRegion = (ArrayList<DetallePedidoBBean>) detallePedidoBean.getListaDetalleRegion();

System.out.println("************listaDetalleRegion "+listaDetalleRegion);

and the result...

************listaDetalleRegion null

What am I doing wrong?

thank you very much

Hi,

Maybe it's the problem with beans configuration? Please check it.

[harut]

Hi Rodrigo, it is not so prefferable way to get the property of the Bean object (in your case collection for dataTable) by the functionality you have mentioned -- (DetallePedidoBBean) request.getAttribute("detallePedidoBean"); .....

It is better to have Bean objects as properties in your "Controller" Bean class(where your Action/ActionListener methods are defined), and simply call getter method of needed property of the Bean object -- in your case

public class AnyControllerBean {

     private DetallePedidoBBean detallePedidoBean;

    ......

     public void recoverTableValuesAction(ActionEvent event) {

           Collection listaDetalleRegion = detallePedidoBean.getListaDetalleRegion();

           ............

     }

}

About the null of your collection -- it is strange in my opinion, and I agree with the Nick's opinion.

But I can suggest to add "a4j:keepalive" declaration for your bean (detallePedidoBean, or if you will go with my suggested way above -- AnyControllerBean) in the top of the page.

After it the problem might be solved.

Regards, Harut.

Hi everybody

Thank you all, I’m checking the configuration as Nick's suggest, something most be wrong, any idea where to start?

Regards Rodrigo

[nbelaevski]

What type of beans configuration are you using: JSF managed beans, Seam, something other?

[rodmen]

Hi Nick, I'm using managed beans

[nbelaevski]

Hi Rodrigo,

Please post managed beans sections from faces-config.xml + beans code.

[rodmen]

Hi, Nick

This is in my faces-config, and the bean is to big so ill attach it

<managed-bean>

<managed-bean-name>pedidoBBean</managed-bean-name>

<managed-bean-class>com.notmusa.comercial.backingBeans.PedidoBBean</managed-bean-class>

<managed-bean-scope>request</managed-bean-scope>

</managed-bean>

<managed-bean>

<managed-bean-name>detallePedidoBean</managed-bean-name>

<managed-bean-class>com.notmusa.comercial.backingBeans.DetallePedidoBBean</managed-bean-class>

<managed-bean-scope>request</managed-bean-scope>

</managed-bean>

<managed-bean>

<managed-bean-name>pedidoMBean</managed-bean-name>

<managed-bean-class>com.notmusa.comercial.managedBeans.PedidoMBean</managed-bean-class>

<managed-bean-scope>request</managed-bean-scope>

</managed-bean>

thank you
