Preserve previously selected row on rich:extendedDatatable after sort

[kbhattac.mailto.kaushik.gmail.com]

Hi,

I'm using a rich:extendedDataTable with sortable rich:column(s). If a row is selected and after that the table is sorted by a column, the row with the same row index remains selected, after the sort (instead of the previously selected row), which is wrong as the result set is now re-shuffled. Is this a bug of richfaces 3.3.1? Here is the used code snippet:

<rich:extendedDataTable width="428px" id="puvTable" border="0" rows="0" var="obj" value="#{allobjs}" 
                             style="border-bottom: 2px #FFF solid;table-layout:fixed;" height="340px"
                             selection="#{tableWithFiltering.selection}" binding="#{tableWithFiltering.table}" 
                             cellpadding="0" cellspacing="0" selectionMode="single" selectedClass="objSelected" noDataLabel="Geen data"
                             onkeydown="jQuery('.content *:input[type!=hidden]:first').attr('maxlength',5);">
                                                
        <a4j:support event="onselectionchange" action="#{tableWithFiltering.select(OBJ_SELECT_EVENT)}" 
                ajaxSingle="true" reRender="objs" oncomplete="reRenderBorder();"/>

        <a4j:support event="onkeyup" action="#{tableWithFiltering.filter(OBJ_SELECT_EVENT)}" 
                ajaxSingle="true" reRender="objs" oncomplete="reRenderBorder();"/>

        <rich:column id="id"
                     filterBy="#{obj.ID}" 
                     filterEvent="onkeyup"
                     headerClass="text-column-indent"
                     styleClass="text-column-indent" 
                     sortBy="#{obj.ID}" 
                     sortable="true" 
                             width="80" 
                             sortIconAscending="#{facesContext.externalContext.requestContextPath}/images/filterdown.gif"
                             sortIconDescending="#{facesContext.externalContext.requestContextPath}/images/filterup.gif"
                             sortIcon="#{facesContext.externalContext.requestContextPath}/images/filternone.gif">
           <f:facet name="header">
                        <h:outputText styleClass="headerText" value="#{messages['beheren.obj.filter.id']}"/>
                </f:facet>
                <h:outputText value="#{obj.ID}"/>
        </rich:column>

        ...
</rich:extendedDataTable>

Here's the Seam component:

@Scope(EVENT)
@Name("tableWithFiltering")
public class FilterableTableSelectionSupport {

    protected Object selectedEntity;
    private HtmlExtendedDataTable table;
    private SimpleSelection selection;

    public void select(String event) {

        if (selection != null) {
            log.debug("in tablerow select(event)");
            doSelect();
            String eventName = isEmpty(event) ? "tableRow.selected." + selectedEntity.getClass().getSimpleName() : event;
            Events.instance().raiseEvent(eventName, selectedEntity);
        }
    }
    
    public HtmlExtendedDataTable getTable() {
        return table;
    }

    public void setTable(HtmlExtendedDataTable table) {
        this.table = table;
    }

    public SimpleSelection getSelection() {
        return selection;
    }

    public void setSelection(SimpleSelection selection) {
        this.selection = selection;
    }
}
