This was happening only on IE8 (native and CoRD). It was working correctly on Chrome and Firefox.
The solution is to call .height(‘auto’) after the dialog is created.
$(document).ready(function() { $('#phoneDataButton').click(function() { $('#phoneDataSearchForm').dialog({ modal:true, width: 700, close: function() { $('#phoneSearchResults').html(""); location.reload(true); } }).height('auto') }) })
