Fancybox with $.ajax conflict "TypeError: loading is undefined"

Fancybox with $.ajax conflict "TypeError: loading is undefined"

Hi friends,

I'm doing a web site where i have a fancyBox, the code bellow:

$.fancybox({scrolling:'no',href:'MyPage.aspx?param='+carreserved,autoScale: false, overlayOpacity: '0.8', hideOnOverlayClick: false, showNavArrows: true,type: 'iframe',width:'100%',height:'400%',onClosed:function(){
      showGreyBox();
      }});

When i close the fancy box, call the method showGreyBox(), code bellow:

        function showGreyBox() {
            try {
                //carrega pagina com box dentro de div greyBoxAlign
                $.ajax({ type: "GET", url: "MyPage.aspx" }).done(function (data) {
                    $("#greyBoxAlign").html(data);
                    var verifyRese = $("[id$=_INFMENT]").val();                    
                });
            } catch (ex) {
                alert(ex);
            }
        }

So, this method make a ajax request when close the fancybox. When i try to call the fancybox again show the message "cannot call method 'hide' of undefined". I found some resolutions, speaking this error is a conflit. I tried many ways to solve this problem with the method noConflit(), but any one worked.

Can some body help me with this problem?

thank you
