phpMyDatagrid, problem s AJAXem

Dobrý den,
snažím se zprovoznit phpMyDatagrid (http://www.gurusistemas.com/…datagrid.php).
Momentálně mám tento presenter:

<?php
class KomponentsPresenter extends BasePresenter
{
	var $objGrid;

	public function getModel()
	{
		return new KomponentsModel;
	}

	public function actionDefault($ident) {

		$objGrid = new datagrid('phpmydatagrid.class.php','1');
		$objGrid -> friendlyHTML();
		$objGrid -> pathtoimages("../css/datagrid/images/");
		$objGrid -> closeTags(true);
		$objGrid -> form('komponents', true);
		$objGrid -> methodForm("get");
		$objGrid -> total("cena");
		$objGrid -> searchby("id,druh,jmeno,cena");
		//$objGrid -> linkparam("sess=".$_REQUEST["sess"]."&username=".$_REQUEST["username"]);
		$objGrid -> decimalDigits(2);
		$objGrid -> decimalPoint(",");
		$objGrid -> conectadb("localhost", "user", "pass", "db");
		$objGrid -> tabla ("komponenty");
		$objGrid -> buttons(true,true,true,true);
		$objGrid -> keyfield("id");
		$objGrid -> salt("salt");
		$objGrid -> TituloGrid("phpMyDataGrid Sample page");
		$objGrid -> datarows(5);
		$objGrid -> paginationmode('links');
		$objGrid -> orderby("id", "DESC");
		$objGrid -> noorderarrows();
		$objGrid -> FormatColumn("id", "ID", 5, 5, 1, "50", "center", "integer");
		$objGrid -> FormatColumn("jmeno", "Name", 30, 30, 0, "150", "left");
		$objGrid -> FormatColumn("cena", "Cena", 5, 5, 0, "50", "right");
		$objGrid -> FormatColumn("druh", "Status", 5, 5, 0, "60", "left",
 		"select:1_cpu:2_gpu:3_hdd");
		$objGrid -> setHeader();
		$this->objGrid = $objGrid;
	}



	public function renderDefault($ident)
	{
		$this->template->grid = $this->objGrid;
	}


}
?>

a šablonu:

{block content}

	<h3></h3>
	<div id="nahledCont">
	{$grid->ajax("silent")}
	 {$grid->grid()}
	 {$grid->desconectar()}

</div>

což vzniklo podle funkčního příkladu:

$objGrid -> setHeader();
?>
</head>

<body>
<?php
$objGrid -> ajax("silent");
$objGrid -> grid();
$objGrid -> desconectar();
?>
</body>
</html>

Příklad funguje bez problémů, editace se projeví v db, atd..
Pokud je ovšem přepsán do presenteru, načte data bez problému, ale při jakékoli akci zůstane vyset na loadingu. Z logu Apache jsem vyčetl, že se AJAX snaží přistupovat na index.php, kde samozřejmě nedostane odpověď.
Jak správně zajistit funkčnost AJAXu?
Popř. nevíte o nějaké komponentě schopné zajistit funkci datagridu s editací (o Editable Datagrid v extras vím, ale developer preview ve mě nebudí moc důvěry).

Předem děkuji za všechny rady.
S pozdravem
