Get row Values of RichDataTable

[godoy]

Is there a way to get the column values of a richDataTable through the binding attribute

can get the values of the header, now I need a way to read tds table rows,

but only the rows that are being displayed on the table, I can not use the getValue () of dataTable

Anyone know how to solve this?

see my code

<rich:dataTable id="racpTb" value="#{racpMBean.model}" var="item" binding="#{racpMBean.tb}" >

                                                  <rich:column>

                                                            <f:facet name="header"> 

                                                                                <h:outputText value="Número - Ação" />  

                                                            </f:facet>

                                                            <h:outputText value="#{item.numeroDocumento} - " />

                                                  </rich:column>

...

and in bean:

// i get values from facet header

HtmlDataTable tb = new HtmlDataTable();

          public void runConversion(ActionEvent evt) {

                    List<UIComponent> colunas = tb.getChildren(); 

for (UIComponent ui : colunas) {

                              List<UIComponent> childs = ui.getFacet("header").getChildren();

                              for (UIComponent child : childs) {

                                        if (child instanceof HtmlOutputText) {

                                                  HtmlOutputText out = (HtmlOutputText) child;

                                          out.getAttributes();

                                        }

                              }

                    }

Any idea?

Thanks.

You have to use a DataVisitor to walk the tables model.

public void walkExtDT(String id) throws IOException {

    FacesContext ctx = FacesContext.getCurrentInstance();

    UIComponent component = ctx.getViewRoot().findComponent(id);

    log.debug("component #0", component);

    if (component != null && component instanceof HtmlExtendedDataTable) {

      final HtmlExtendedDataTable t = (HtmlExtendedDataTable) component;

      t.captureOrigValue(ctx);

      DataVisitor visitor = new DataVisitor() {

        @Override

        public void process(FacesContext context, Object rowKey, Object argument)

            throws IOException {

          t.setRowKey(rowKey);

          Iterator<UIColumn> colIter = t.getChildColumns();

          while (colIter.hasNext()) {

            UIColumn col = colIter.next();

            List<UIComponent> children = col.getChildren();

            for (UIComponent c : children) {

              if (c instanceof UIOutput) {

                System.out.println(((UIOutput) c).getValue());

              }

            }

          }

        }

      };

      t.walk(ctx, visitor, null);

      t.restoreOrigValue(ctx);

      t.setRowKey(null);

    }

  }

ah sorry, my example is for the extendedDataTable. To use with the standard datatable you'll have to change to HtmlDataTable. This should do the trick.

No componentbinding required! Just pass the clientId of the table to the method.
