jQuery UI Tabs, how to solve TypeError: ui.jqXHR.error is not a function?

I am using the latest version jQuery UI for tabs but i get the following error in

TypeError: ui.jqXHR.error is not a function

Here is my actual code that manages tabs

$(function() {
        $( diaise_et_id ).tabs({

            beforeLoad: function( event, ui ) {
                ui.jqXHR.error(function() {
                    ui.panel.html(
                        "Couldn't load this tab. Please check your internet connection or connection to the server. " +
                        "Praise God forever More" );
                });
            }
        });

And this is how i call the function

<script type="text/javascript" language="javascript">
pour_les_tabs("#tabs_20");
</script>

I am still seeing

TypeError: ui.jqXHR.error is not a function.

What could probably be the problem and how to solve it please ?

Thanks
