How to popule a grid (rich:extendedDataTable)?

[grinvon]

I have done the grid design using this component. In the value attribute I have setted: value="#{MyBean.lstClients}, where lstclients is a List class type.

The problem is the table don´t render with populated datas. I saw in somewhere I need to build a DataModel object to populate the table, but how?

Thanks all.

I´m trying to use SerializableDataModel, If I get some result I post again here.

Hello,

ExtendedDataTable works with List type, you do not need to create your own data model. Can you please post full page and bean code?

Thank you nbelaevski, for your answer.


My JSP

 <h:panelGrid columns="1">
 <rich:extendedDataTable id="tblComissao" value="#{ComissaoLst.lstComissao}" var="tblComissao"
 width="800px" height="250px" selectedClass="dataTableSelectedRow"
 sortMode="single" selectionMode="multi" selection="#{extendedDT.selection}"
 rowKeyVar="rkvar" tableState="#{extendedDT.tableState}">
 <rich:column id="unidade" headerClass="dataTableHeader" width="150" label="Unidade" sortable="true"
 sortBy="#{tblComissao.unidadeComissao}" sortIconAscending="dataTableAscIcon"
 filterBy="#{tblComissao.unidadeComissao}"
 sortIconDescending="dataTableDescIcon">
 <f:facet name="header">
 <h:outputText value="Unidade" />
 </f:facet>
 <h:outputText value="#{tblComissao.unidadeComissao}" />

 </h:outputText>
 </rich:column>
 <rich:column id="chefeImediato" width="150" headerClass="dataTableHeader" label="ChefeImediato"

 <f:facet name="header">
 <h:outputText value="Servidores Avaliáveis" />

 <h:outputText value="Situação" />
 </f:facet>
 <h:outputText value="#{tblComissao.situacao}" />
 </rich:column>
 </rich:extendedDataTable>
 </h:panelGrid>

My bean where I populate lstComissao

public class ComissaoLst {

 private List<Comissao> lstComissao;

 public ComissaoLst() {
 // this method get all rows from JPA
 lstComissao = ComissaoBS.getInstancia().obterTodas();
 }

 public List<Comissao> getLstComissao() {
 System.out.println("Getting all rows...");
 lstComissao = ComissaoBS.getInstancia().obterTodas();
 return lstComissao;
 }

}

There are some rows at database, I don´t know why the faces component (extendedDataTable) don´t render these rows.

Thank u.

and the same code works with rich:dataTable?

You may see our example at demosite. It uses simpel List also..
