Hi, I ran into a problem when using a multi select list in a form submitted through ajax. The name of the select element is something like foo[]. When multiple entries are selected the browser creates form data like foo[]=1&foo[]=2&foo[]=4 (url encoded of course). Rails then creates an array ["1","2","4"] for foo''s entry in the parameter hash. Prototype OTOH creates an url like foo[]=1,2,4 which isn''t recognized by rails and I end up with an array ["1,2,4"] in the parameter has, which does not work for updating a habtm relationship. Should this be considered a bug in prototype (Form.serialize should work the same way the browser works)? Or is it a rails problem? Morus
