OK, it seems you need to use a separate server, such as BlazeDS, to access the PUT and DELETE methods. I have not tried it personally, I feel that it is completely lame, that this should be the only solution. When I used FLEX 3 with Rails 2, I was able to achieve RESTfulness by doing "_method = PUT hack". But, when I upgraded to Rails 3, it no longer works :(
, . (Rails 3 - "_method = PUT" , ?), .... , FLEX - , Rails 3 _method = PUT.
