AJAX error callback function executes twice in IE 6+

[misxa]

AJAX error callback function executes twice in IE 6+ if the XML file is unavailable because it doesn't exist. The code below is the current code which produces this problem. The UI dialog in the error function pops up twice in IE. The same thing happens with simple alert() function. Other browsers work just fine;

Code:

$.ajax({

type: "GET", url: "vjezbe/vjezbe.xml", dataType: "xml", success: xmlSuccess, error: xmlError

});

function xmlError(xhr, message, optional) {

$('<p class="poruka">XML podaci sa vježbama su nedostupni!</p>').dialog({

modal: true, title: 'Poruka', buttons: {

OK: function() {

$( this ).dialog( "close" );

}

}, resizable: false

});

}
