Hi, I''ve been doing a lot of rewriting of dragdrop.js. I''ve covered at least eight open tickets, made multiple selection of draggables, droppables can accept multiple items at a time, added 21 consistently-named callbacks and have reorganized the code. I''m working on adding more things to Sortable now. I''m no JavaScript expert, this is my first project, and I

Hi, I''ve been working on new ideas for a JavaScript drag and drop library. I haven''t found a drag and drop library flexible enough for my needs and I think I have come up with something that is generally worthwhile. I use the DOM and Event utilities from Yahoo!

To have a look at the new "ghosting" option in dragdrop.js, get yourself the latest SVN trunk and play around with the dragdrop_functional_4.html and sortable_function_ghosting.html test files.

But for the application this is really GET /cart_item/new/5 or even better /cart_item/new?cart_item[product_id]=5 When the customer clicks add_to_cart they POST /product/5/show so that the url doesn''t confuse the user when any validation errors occur.

Hi, I''ve read the Agile Rails book''s chapter on ActionMailer a few times. Seems pretty straight forward. Unfortunately I can''t get my application to actually send mail. I uploaded my application to the web server and tried to get a mail message sent. Nothing happened. I looked in the log file and it says Sent mail: From: service@freedomkilts.com To:

Hi folks, I''m in the process of updating a mostly-server-side web app to 21st century functionality, using the prototype.js etc packages.

Hi, I am changing a very standard old school website to rails. When I make the change to rails, all of the old urls will not be valid.

Hi, I''ve just been having a look at the scriptaculous drag-n-drop library, which looks exceedingly good. I''m running across a show-stopper here, though - something that''s cropping up in both the online demos and my own test scripts. If I set up two lists so that I can drag items between them, then if either list becomes empty, I can''t drag elements back into

Hi, In the last few days I''ve been working a lot on rewriting the dragdrop.js code. I''ve made changes for what I think is stronger object-oriented design and made more parallels between how Droppbables and Draggables are coded and instantiated. I have multiple selection and dragging of draggables working and droppables can accept multiple draggables in one drop. There are some
