method post does not work

1. Method post won't work. I have jquery 1.3.2 and UI 1.7.3. I get an error "Uncaught TypeError: Object # has no method 'post'" on line 104 of jquery_ui_dialog_parent.js. This line looks like old-style coded. Mb. replace $.post by $.ajax?.

2. Close from parent JS also don't work. Here is a wrong selector in Drupal.jqui_dialog.close function. Instead of $('#jq-ui-dialog-iframe').dialog('close') we need to use $(Drupal.jqui_dialog.container).dialog('close').
