Missing argument

I get this error:

Warning: Missing argument 1 for dataGrid::render(), called in /home/public_html/browse.php on line 92 and defined in /home/public_html/class.datagrid.php on line 636

I'm not exactly familiar with xtemplate, and I know this is only a warning but is outputting no results :(

Any hints?

I'm getting the same error message too.

I've tried putting the name of the page as an argument...
$grid->render("example4.php");
Which then gets rid of the error but only produces a plain list, not a formatted grid.

Also, where is the 'documentation' that is referred to on several pages?
All I have is a readme.txt file which has a couple of lines warning about the mySql db.

Is this class still being maintained?

$grid->render(); should contain a Boolean
