jquery UI dialog is not draggable after upgrading to version 1.11

[anonymous]

Im have upgraded jquery-1.11.0 from 1.7.2 after which, jquery ui dialog doesnt seem to work properly. It is not draggable. When I tried to drag the dialog, it says "elem.ownerDocument is null". I have tried a work around which I found on net , to return null value if elem.ownerDocument is null, as below

if (elem.ownerDocument == null) {

return null;

} else {

return elem.ownerDocument.defaultView.getComputedStyle(elem, null);

}

now the jquery dimensions file throw error that "parent is null" in the line

if (parent.tagName.toLowerCase() == 'body'

parent.tagName.toLowerCase() == 'html') {

jquery-ui-1.10.3.css is the css version that Im using
