ajax callbacks can't apply #attached

subscribe. You sure know how to find them!

This is quite troubling. I am trying to build an ajax element that requires dynamic js (http://drupal.org/project/imagefield_crop), and I have no way to implement that without being able to add dynamic js settings.
I've also tried calling plain old drupal_add_js() in the process function, but that doesn't seem to work as well.

Even a workaround until this is properly fixed would be appreciated.

Thanks @merlinofchaos for pointing me to #561858: [Tests added] Fix drupal_add_js() and drupal_add_css() to work for AJAX requests too by adding lazy-load to AJAX framework which blocks this.

Setting to critical based on the discussion in #561858: [Tests added] Fix drupal_add_js() and drupal_add_css() to work for AJAX requests too by adding lazy-load to AJAX framework. Not sure why you are marking this as postponed, as it clearly does not work as intended.

Postponed = waiting on something else. It's postponed until the other issue is fixed.

That is called "blocked" in other issue management systems.

It should be active for our purposes here, so it doesn't go off the radar. I think we use "postponed" only when a decision has been made not to do it for the foreseeable future.

Blocked for now by #561858: [Tests added] Fix drupal_add_js() and drupal_add_css() to work for AJAX requests too by adding lazy-load to AJAX framework. Taking this one out of "critical" though - although I think the case can be made that that one is critical, it would have to be made here for this one.

Attached is a bug demo module that demonstrates the exact description by fago. Use the "AJAX bugs: AJAX adds fieldset" menu item.

Marked #810578: #collapsible not working for elements rendered via AJAX as a duplicate of this one.

Also forbids #states in ajax updated parts of forms - which is sad :-).

I believe this is a straight up duplicate of #561858: [Tests added] Fix drupal_add_js() and drupal_add_css() to work for AJAX requests too by adding lazy-load to AJAX framework. That's the issue that's dealing with the problem that calls to drupal_add_(css|js)() don't result in CSS/JS being added during an AJAX response. When that's fixed, this issue's problem will be fixed too, as #attached does correctly call drupal_add_*().

#561858-78: [Tests added] Fix drupal_add_js() and drupal_add_css() to work for AJAX requests too by adding lazy-load to AJAX framework now has a patch from merlinofchaos that gives us lazy loading and makes #attached and #states work. Please go over there and review/improve it.

#561858: [Tests added] Fix drupal_add_js() and drupal_add_css() to work for AJAX requests too by adding lazy-load to AJAX framework got in, but ['#attached']['js'] or drupal_add_js() still fail to add new scripts to the page when executed in an ajax callback.
(js settings are correctly merged though)

Re: myself in previous comment:
Never mind. #1962236-4: Scripts added using drupal_add_js() are never added to the page after an AJAX callback from @Wim Leers explains that this is a weirdness in jQuery <=1.9 that the scripts do not appear to be added to the DOM, but they are still correctly loaded.
Bumping jQ to 1.10 with latest release of jquery_update fixes the weirdness (the additional <script> tags do appear in the DOM)
