Any know any RIA (with IDE) which follow de DRY concept and can be integrated with Rails?
I maked tests with Flex, but is a lot of code and lost many of the advantages of Rails (you need the definition of several models in several sides XML configuration, etc). There is a plugin called RestfulX that works well to generate the CRUD, but again, each time something has to change too much time is lost.
I've done some tests with ExtJS but the unique IDE that y found is not good.
There is JavaFX that Netbeans supports. You can probably use it with jRuby but I didn't test it.
