Structures_DataGrid requestPrefix for paging

I am trying to implement DataGrid and am having trouble changing the requestPrefix for paging. I tried to simply do this: // build DO $module = DB_DataObject::factory('Module'); // setup datagrid $dg =& new Structures_DataGrid(5); $dg->bind($module); //set prefix for paging $dg->renderer->requestPrefix = "L"; // Show data $dg->render(); echo $dg->renderer->getPaging(); The problem is that my application already uses the default "page" variable for displaying pages. I need to change the prefix so that it does not conflict with my application to something else (e.g. Lpage). However, when I try this my page does not display correctly. It seems that the renderer is still relying on the "page" variable and goes nuts. I end up with a blank page followed by navigation buttons. In other words, the grid does not display. Anyone have ideas on how to correctly set the requestPrefix variable? Thank you.
