Dynamic extendedDataTable

[trigun]

Hi,

i try to create a extendedDataTable from a Bean, Working on IBM WAS 7 and Richfaces 3.3.3 Final:

my .xhtml looks like this:

<h:form id="tcForm">
     <h:panelGroup id="panelTestTbl" binding="#{testCaseTable.dataTableGroup }" />
       <rich:contextMenu id="ctxMenu" binding="#{testCaseTable.ctxMenu }" >
       </rich:contextMenu>
 </h:form>

my Bean:

public class TestCaseTable {
          private UIExtendedDataTable custumExtDataTbl;
          private HtmlPanelGroup dataTableGroup; // Placeholder.


     // Getters -----------------------------------------------------------------------------------


    public HtmlPanelGroup getDataTableGroup() {
        // This will be called once in the first RESTORE VIEW phase.
        if (dataTableGroup == null) {
            populateDataTable(); // Populate datatable.
        }
        return dataTableGroup;
    }


    // Setters -----------------------------------------------------------------------------------


    public void setDataTableGroup(HtmlPanelGroup dataTableGroup) {
        this.dataTableGroup = dataTableGroup;
    }

          public void populateDataTable() {
                   
ExpressionFactory elFactory = FacesContext.getCurrentInstance().getApplication().getExpressionFactory();
                    ELContext elContext = FacesContext.getCurrentInstance().getELContext();
                    Application app = FacesContext.getCurrentInstance().getApplication();
  
                    /* Create the HtmlExtendedDataTable */
                    custumExtDataTbl = (UIExtendedDataTable) app.createComponent(UIExtendedDataTable.COMPONENT_TYPE);
                    custumExtDataTbl.setValueExpression("selection",
                                        elFactory.createValueExpression(elContext, "#{testCaseTable.selection}", Selection.class));
                    custumExtDataTbl.setValueExpression("value",
                                        elFactory.createValueExpression(elContext, "#{testCaseTable.parentTestCases}", ArrayList.class));
                    custumExtDataTbl.setVar("testCase");
                    custumExtDataTbl.setRows(25);
                    custumExtDataTbl.setId("customTestTbl");
  
                    /* Create the columns */
                    UIColumn namCol = (UIColumn) app.createComponent(UIColumn.COMPONENT_TYPE);
                    custumExtDataTbl.getChildren().add(namCol);
  
                        HtmlOutputText idHeader = new HtmlOutputText();
                       idHeader.setValue("NAME");
                       idHeader.setId("nameHead");
                       namCol.setHeader(idHeader);
                       namCol.setId("colName");
        
                      HtmlOutputText idOutput = new HtmlOutputText();
                      idOutput.setValueExpression("value",
                            elFactory.createValueExpression(elContext, "#{testCase.name}", String.class));
                       idOutput.setId("colNameTxt");
                       namCol.getChildren().add(idOutput);
  
                    // Finally add the datatable to <h:panelGroup binding="#{myBean.dataTableGroup}">.
                       dataTableGroup = new HtmlPanelGroup();
                       dataTableGroup.getChildren().add(custumExtDataTbl);


          }

I get no errors, but my Table did noch show some Data. Even the header is not displayed. Only the borders of the Table.

Any ideas ? Thank you
