Displaying a link in a tableView

Question

Hi,
I am trying to display a link in column of a tableview in a jsp page.
the source code is:
     public void initAttachmentsModel() {
          Vector colName = new Vector(2);          
          colName.addElement("File Name");
          colName.addElement("URL");
          attachmentsModel = new DefaultTableViewModel(attachmentsList, colName);
          TableColumn col = attachmentsModel.getColumn("URL");
          col.setType(TableColumnType.LINK);
          col.setEncode(false);
But no link is displayed within the tableview.
I also tried setUserTypeCellRenderer() and still no results.

Hi Aviad,
You can do this in two ways. Populate the value of all columns in Table Model.
<u>I Way</u>: Set the column type as Link in TableView Model.
<hbj:tableView  id="myTableView"
                model= "myTableViewBean.model"
                design = "ALTERNATING"
                headerVisible = "true"
                footerVisible = "true"
                fillUpEmptyRows = "true"
                selectionMode = "MULTISELECT"
                navigationMode = "BYLINE"
                headerText = "<h3>tableView</h3>"
                visibleFirstRow = "1"
                visibleRowCount = "4"
                onNavigate="onNavigate" >
<%
myTableView.setColumnType(TableColumnType.LINK,column no);
%>
  </hbj:tableView>
<u>II Way</u> Set the column type as TableColumnType.USER and write the cell renderer.
<%
myTableView.setColumnType(TableColumnType.USER,column no);       
myTableView.setUserTypeCellRenderer(new TableViewCellRenderer()); %>
In Cell Renderer "TableViewCellRenderer.java"
import com.sapportals.htmlb.*;
import com.sapportals.htmlb.rendering.IPageContext;
import com.sapportals.htmlb.table.ICellRenderer;
import com.sapportals.htmlb.table.TableView;
public class TableViewCellRenderer implements ICellRenderer {
    public void renderCell(int row, int column, TableView tableView, IPageContext rendererContext) {
        if (column == 1) {
         Link mylink = new Link();
         String linkText = tableView.getValueAt(row, 
                           column).toString();
         mylink.addText(linkText);
     // Set the renderer
            ddlb.render(rendererContext);
Hope this helps.
