The dialog not always appears in the center/bottom vertically. Workaround supplied.

[MindStorm]

I have the following code

$.ui.dialog.defaults.bgiframe = true;

$(document).ready(function(){
	$("#dialog-box").dialog({
		width: 700,
		autoOpen: false,
		modal: true,
		position: ['center','middle']
	});
});

function show_dialog(params)
{
	$("#dialog-box").load(
		"http://examle.com"
		{ params: params},
		function() {
			$("#dialog-box").dialog("open");
		});
}

When the funcion show_dialog is called many times and the heigth of the content (obtained from ajax) is variable, p.e. content have images in different heights: the dialog appears a little below of the middle or a little below of the bottom of the visible page, surpassing the limits of the window. Tested on Firefox 3.0.5 and Internet Explorer 7.

I can't figure out the cause of this behavior yet. Maybe an ajax related issue or the sizing/positioning calculations is missing someting.

But a temporal workaround to avoid this behavior is to use the setTimeOut() function when open the dialog:

setTimeout(function(){ $("#sociales-dialogo").dialog("open"); }, 100);

The ideal situation is avoiding the setTimeOut, but setting it at 100 - 150 milliseconds will be imperceptible in the meanwhile. I hope that this bug is fixed in the next realease.

I will try to upload an example about this bug later.

I chose the improper component. I chose ui.core instead of ui.dialog. Sorry for the mistake.

I found what's causing bad positioning. When the content has images with various heights and are loaded for first time, it causes a miscalculation because the image is not completely loaded yet.

I fixed the problem by adding the heights and width of the images (with CSS or with the attributes of img tag). You no longer need to use setTimeout.

As noted by the reporter, the dialog is positioned properly and the size of the content changes after it has been shown.
