my site's frontpage has a CSS3-only object (fwiw, an accordion). i've added a page .js init that contains (function($) { Drupal.behaviors.frontpage = { attach: function(context,settings) { --> window.location.hash = '#pane1'; which, on document.ready 'jumps to' the accordion "pane1" anchor tag, opening it as default. that init is loaded in a preprocess-page hook, --------------------------------------- <?php function sub_omega_alpha_preprocess_page(&$vars) { ... drupal_add_js( $pgn_theme_dir . '/js/all-p-init.js', array( 'type' => 'file', 'scope' => 'header', 'group' => JS_LIBRARY, 'every_page' => FALSE, 'weight' => -99, 'defer' => FALSE, 'cache' => TRUE, 'preprocess' => TRUE, ) ); if (drupal_is_front_page()) { ... drupal_add_js( $pgn_theme_dir . '/js/fp-init.js', array( 'type' => 'file', 'scope' => 'header', 'group' => JS_LIBRARY, 'every_page' => FALSE, 'weight' => -99, 'defer' => FALSE, 'cache' => TRUE, 'preprocess' => TRUE, ) ); } else { drupal_add_js( $pgn_theme_dir . '/js/not-fp-init.js', array( 'type' => 'file', 'scope' => 'header', 'group' => JS_LIBRARY, 'every_page' => FALSE, 'weight' => -99, 'defer' => FALSE, 'cache' => TRUE, 'preprocess' => TRUE, ) ); } ;} --------------------------------------- this works as expected if at .../admin/config/development/performance JavaScript agg is enabled, -------------------------------------- Bandwidth optimization External resources can be optimized automatically, which can reduce both the size and number of requests made to your website.

I.e., that 'jump to' the anchor is not in-effect. In this case, the browser URL bar in-correctly displays https://test.net/ i.e., NO anchor tag. Since Omega, LabJS & Drupal core all could ostensibly play a part, I'm not sure what the singular cause of this difference in behavior might be. My gut tells me it's likely .js load-order being handled differently in the two cases. I'm not yet convinced ... Here's a diff of the page's ViewSource for the two cases -- js aggregation ON, and js aggregation off: --- js-agg-OFF.txt 2012-07-12 12:14:43.931189584 -0700 +++ js-agg-ON.txt 2012-07-12 12:15:30.382410736 -0700 @@ -76,30 +76,11 @@ </script> <script> // LABjs exclusion -$L = $L.script(["https://test.net/sites/all/modules/contrib/jquery_update/replace/jquery/1.7/...", -"https://test.net/misc/jquery.once.js", -"https://test.net/sites/all/modules/contrib/labjs/replace/drupal.js", -"/data/webapps/cdn/www.pgnetwork.net/js/dialogextend/jquery.dialogextend.pack.js", -"https://test.net/sites/all/themes/sub_omega/js/all-p-init.js", ==> -"https://test.net/sites/all/themes/sub_omega/js/fp-init.js", -"https://test.net/sites/all/modules/contrib/jquery_update/replace/ui/ui/minif...", -"https://test.net/sites/all/modules/contrib/jquery_update/replace/ui/ui/minif...", -"https://test.net/sites/all/modules/contrib/jquery_update/replace/ui/external...", -"https://test.net/sites/all/modules/contrib/jquery_update/replace/ui/ui/minif...", -"https://test.net/sites/all/modules/contrib/jquery_update/replace/ui/ui/minif...", -"https://test.net/sites/all/modules/contrib/jquery_update/replace/ui/ui/minif...", -"https://test.net/sites/all/modules/contrib/jquery_update/replace/ui/ui/minif...", -"https://test.net/sites/all/modules/contrib/jquery_update/replace/ui/ui/minif...", -"https://test.net/sites/all/modules/contrib/jquery_update/replace/ui/ui/minif...", -"https://test.net/sites/all/modules/contrib/views/js/jquery.ui.dialog.patch.j...", -"https://test.net/sites/all/modules/contrib/admin_menu/admin_devel/admin_deve...", -"https://test.net/sites/all/modules/contrib/contentanalysis/contentanalysis.j...", -"https://test.net/sites/all/modules/contrib/contentoptimizer/contentoptimizer...", -"https://test.net/sites/all/modules/contrib/resp_img/resp_img.js", -"https://test.net/sites/all/modules/contrib/panels/js/panels.js", -"https://test.net/sites/all/modules/contrib/google_analytics/googleanalytics....", -"https://test.net/sites/all/themes/contrib/omega/omega/js/jquery.formalize.js", -"https://test.net/sites/all/themes/contrib/omega/omega/js/omega-mediaqueries...."]); +$L = $L.script(["https://test.net/sites/default/files/js/js_LP6eaYL3pE-X3CISx4yhE59L-xvxjYoQE...", ==> +"https://test.net/sites/default/files/js/js_r9tk7PwLQm4lcqNXt_DTdEfATxWT8fTav...", +"https://test.net/sites/default/files/js/js_4ZrSfhQVOw6i9znJCZe7jUN7u2jzAKWco...", +"https://test.net/sites/default/files/js/js_EtFFZ9lbcSXbmEJ6DdbkcmBheDx1eo7kt...", +"https://test.net/sites/default/files/js/js_SqSPKHRdgR49lUgM5xyDHyrUmB1wUEtOw..."]); </script> <script> $L = $L.wait(function() { @@ -108,7 +89,7 @@ </script> <script> $L = $L.wait(function() { -jQuery.extend(Drupal.settings, {"basePath":"\/","pathPrefix":"","ajaxPageState":...width: 1220px)"}}}}); +jQuery.extend(Drupal.settings, {"basePath":"\/","pathPrefix":"","ajaxPageState":...width: 1220px)"}}}}); }); </script> <!--[if lt IE 9]><script src="https://html5shiv.googlecode.com/svn/trunk/html5.js"></script><![endif]--> where inside sites/default/files/js/js_r9tk7PwLQm4lcqNXt_DTdEfATxWT8fTavO9qp3cJB3E.js I find the relevant JS ...

Presuming that load-order is the issue, I'm working, somewhat randomly atm, at finding a load-order in the unaggregated case that functions correctly. Any informed guidance as to what may specifically be the cause of this 'jump to tag' sensitivity to js aggregation state would be appreciated.
