ActiveScaffold - RJS Error with Firefox 3 and Safari 3.1

Recently I'm testing in Firefox 3 the "admin" section - implemented using ActiveScaffold - of a Rails application we made.

I'm getting RJS Errors when trying to update a record:

• TypeError: $$("#admin__operator_details-update-151-form a.cancel").first().link is undefined
• $$("#admin__operator_details-update-151-form a.cancel").first().link.close_with_refresh();

The issues is already reported as #553

The summary is that the problem lies within the deprecated getElementsByClassName function in the active_scaffold.js.

To fix (thanks to Eric Bjorkvall) just replace in files:

• /public/javascripts/active_scaffold/default/active_scaffold.js
• /vendor/plugins/active_scaffold/frontends/default/javascripts/active_scaffold.js

the line: this.adapter.getElementsByClassName('cancel').each(function(elem) { with: this.adapter.select('.cancel').each(function(elem) {

Instead of replacing the original assets of ActiveScaffold I skipped the change on /vendor/plugins/active_scaffold/frontends/default/javascripts/active_scaffold.js and just comment the /vendor/plugins/active_scaffold/init.rb in order to avoid the copy assets on plugin initialization.
