Description:
------------
Unknown class passed as parameter in C:\\php\\PEAR\\Structures\\DataGrid\\DataSource.php on line 365

Test script:
---------------
<?php
require 'Structures/DataGrid.php';

// Instantiate the DataGrid
$datagrid =& new Structures_DataGrid();

// Setup your database connection
$options = array('dsn' => 'mysql://username:password@host/myDB');

// Bind a basic SQL statement as datasource
$datagrid->bind("SELECT * FROM myTable",$options);

// Print the DataGrid with the default renderer (HTML Table)
$datagrid->render();
?>

Expected result:
----------------
I expected to see the output of this script as described by the text in the User Documentation that accompanies it.

Actual result:
--------------
Apache Log: [Fri Apr 28 15:36:52 2006] [error] [client 127.0.0.1] PHP Warning: Unknown class passed as parameter in C:\\php\\PEAR\\Structures\\DataGrid\\DataSource.php on line 365

Line 365 is:

case (is_subclass_of($source, 'db_dataobject')):

Looking through php.net I found the following:

User Comment in is_subclass_of():

"A bug report at http://pear.php.net/bugs/bug.php?id=2975 indicates that the "is_subclass_of" function can return the error message:

Warning: Unknown class passed as parameter

in the event that the class represented by the second argument hasn't yet been instantiated."

So this is a known issue by someone. This is current in version 0.6.3 of this package.
