Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.
Looks like Drupal doesn't generate form_token if the user is anonymous (which is strange, but might have to do with the security of the token generator?). So I needed to make that test conditional.
Maybe not ready for prime time, but worth checking out.
The version has added the ability to target multiple image buttons with the same class (needed by views_ui), refined the technique for only reattaching bindings to the html that has been replaced, and added a prototype for system-wide js->js binding declarations.
This is the first release of this proposed framework. It still has a lot of growing to do. See the read me and examples directory to get an idea you to use it.
