I mangaged to get the ACE editor (http://ace.ajax.org/) working with my qooxdoo project by dropping the required .js and .css files in the resource directory and requiring them with an #asset(...) directive in the sources.
While this is working fine, it just doesn't feel right. Is there a chance to integrate ACE in a way that lets the qooxdoo build scripts integrate it in the big resulting JS and CSS files?
