Hi.

I am trying to implement sorting functionality to my custom dataTable. But the functionlity is not working.

My table header became sortable and even in the fire bug AJAX.Submit() method also invoking when onClick event fires on the table header.

But my table data is not sorting.

Please find my code below.

for (int i = 1; i <= columns; i++) {
                        header = new HtmlOutputText();
                        header.setValue("header" + i);
                        col = new HtmlColumn();
                        col.setId("col" + i);
                        col.setHeader(header);
                        expression = factory.createValueExpression(elcontext, "#{row[" + (i - 1)+ "]}", String.class);
                        body = new HtmlOutputText();
                        body.setValueExpression("value", expression);
                        col.getChildren().add(body);
                        col.setSortable(true);
                        col.setSortIcon("/webuif/images/ascending.gif");
                        col.setSortIconAscending("/webuif/images/ascending.gif");
                        col.setSortIconDescending("/webuif/images/descending.gif");
                        col.setValueExpression("sortBy",expression);
                        getChildren().add(col);                      

My Bean is like below:

private ListDataModel data;

public ListDataModel getData() {
        List<String> listdata = new ArrayList<String>(10);
        listdata.add("one");
        listdata.add("two");
        listdata.add("three");
        listdata.add("four");

        data = new ListDataModel(listdata);
        return data;
    }

Data is properly inserting into my table properly But sorting is not happening.

Is there any thing i missed for sorting functionality.

Any help would really appreciated.

Br,

Gana
