Date popups do not work when they are added by AHAH

after some further testing, the above patch breaks modal dialog functionality if an ahah form is rendered in a ctools modal. What will happen is that the modal will load if you click a link on a page first time round, then if you click on an ahah behaviour, close the modal, then try to re-open it by clicking the link, the javascript will not fire and the page will redirect to the nojs page.

related post - http://drupal.org/node/244025#comment-2546764 , which explains my patch, but the patch seems to break the modal stuff as explained above. any ideas?

commenting out that file makes no difference - the call to drupal_get_js() causes problems with other scripts on the page.
After a bit of further investigation it seems the main problem is because the settings for the AHAH added date_popup field are not passed out through the ahah_helper_render() function.

The new javascript files which are called by calling date_popup_load() and through date_popup_js_settings_id() are also not added.
Could the new JS files be loaded by integrating with the ajax load module, by implementing the _alter() hook before the data is rendered out in JSON?

I am attaching a patch to cover adding the date popup settings back to the form through the ahah render function.
To ensure the date popup will work the js will need to be on the page when the page is loaded, which you can achieve by doing -

    date_popup_load();
    drupal_add_js(drupal_get_path('module', 'date_popup') .'/date_popup.js');
