ui-dialog: why is the dialog-content "removed" (appended to) the dialog-container?


hi jquerers,
when calling:
$(element).dialog(modal: true, buttons: {Cancel: function() {$
(this).dialog('close');}})
the $(element) gets effectively removed on _init() -why? After
canceling a dialog one should be able to reopen the dialog... the
documentation does not mention such cases and in the demo each click
just loads a page (e.g. http://jqueryui.com/demos/dialog/modal-confirmation.html)
there are some confusing line about 'open', 'close' and 'destroy'
which i do not understand:
@ http://jqueryui.com/demos/dialog/#modal-confirmation
