title: DataGrid not rendering
body: <p>I am new to TurboGears2 and by extension ToscaWidgets2. I am following the tutorial given here <a href="http://turbogears.readthedocs.org/en/latest/cookbook/datagrid.html" rel="nofollow">http://turbogears.readthedocs.org/en/latest/cookbook/datagrid.html</a></p>
  
  <p>for creating a basic datagrid. When I view the index page, all I see is this:</p>
  
  <p>class 'tw2.core.params.DataGrid_s_s'</p>
  
  <p>I have also tried using a DataGrid for showing data from an existing DB, but I also get the same above result. Shouldn't there be a .css file that would handle the grid generation/display?</p>
  
  <p>I have checked past tutorials for using DataGrid on TurboGears, and when it comes to displaying the grid, they only show this line:</p>
  
  <p>${grid(value=data} ( or ${grid(data)} in older TG versions).</p>
  
  <p>Since there are no errors being shown, I am at a complete loss here. I have searched online for a solution on this, but I haven't been lucky. Any advice on how to get around this?</p>
  
  <p>Cheers,
  DM</p>
