JQuery UI dialog - *Dialog not a function* error

Question

I am developing a site using pinax. In one of my templates I am trying to open a simple jquery dialog box. However I keep getting the \"Dialog not a function\" javascript er

Answer 1

The answer by Doug Neiner helped really. My case was a bit more complicated, but still comes to same point:

I opened a dialog from Page A which loads Page B like this:

$('#MyDiv').dialog({
    autoOpen: false
})
$("#MyDiv").load("PageB.aspx", function () {
    $("#MyDiv").dialog("open");
});

The problem is that both Page A and B had included jQuery. Be aware: if you are loading another page into a dialog, it does not need to include same js.
