FYI: http://dev.rubyonrails.org/ticket/4888
This patch fixes a (presumably mistaken) rollback a while ago, in Prototype's Abstract.EventObserver.prototype.initialize method. In rev 3378, DHH changed it to allow an optional third parameter [1]. But in rev 3795, sam changed it back [2]. As a result, observe_field's :on option [3] is ignored. So either observe_field's documentation should be fixed, or the change should be re-applied. This patch does the latter. -Scott [1] http://dev.rubyonrails.org/browser/trunk/actionpack/lib/action_view/helpers/javascripts/prototype.js?rev=3378#L1401 [2] http://dev.rubyonrails.org/browser/trunk/actionpack/lib/action_view/helpers/javascripts/prototype.js?rev=3795#L1564 [3] http://api.rubyonrails.org/classes/ActionView/Helpers/PrototypeHelper.html#M000421 _______________________________________________ Rails-core mailing list Rails-core@lists.rubyonrails.org http://lists.rubyonrails.org/mailman/listinfo/rails-core
