Dynamically populating ExtendedDataTable

[krayaprolu]

Hi,

We are evaluating Richfaces to replace our old UI using old technology. I am currently evaluating Richfaces v3.3.3.Final

As part of it, I am trying to populate Extended Data Table from a backing bean in Java. After a long struggle, I am able to display the Extended Data table, but the data would not show up. If I directly define in the Extended Data Table in XHTML, the data is displayed, can anyone please help me.

Java Code:

public HtmlExtendedDataTable getPreviewTable(List data, List columnNames) {
        HtmlExtendedDataTable previewTable = new HtmlExtendedDataTable();
        ArrayList previewData = transposeData(data);

        int cntr = 0;
        Iterator itr = previewData.iterator();
        while (itr.hasNext()) {
            List columnData = (List) itr.next();
            String columnName = columnNames.get(cntr++).toString();
            HtmlColumn column = new HtmlColumn();

            column.setLabel(columnName);
            column.setSortable(true);
            column.setSortBy(columnName);
            column.setId(columnName);
           
            HtmlOutputText header = new HtmlOutputText();
            header.setValue(columnName);
            header.setStyle("text-align:center; font-size:12px; font-weight:bold");
           
            column.setHeader(header);
           
            HtmlOutputText colData = new HtmlOutputText();
            colData.setValue(columnData);

            column.getChildren().add(colData);
            previewTable.getChildren().add(column);
           
        }

        return previewTable;
    }

XHTML code:

<rich:extendedDataTable binding="#{newUI.previewData}"
                                    var="item"
                                    height="275px"
                                    width="740px"
                                    id="populateTable" />

I am using Glassfish v2.1.1 and spring webflow.

Thanks in advance.
