grails vs gaelyk for appengine

Failed to do small prototype with Grails on appegine, poor grails-gae integration, critical eclipse bugs, gotchas with deploy tools.

Tried Gaelyk - worked well: very lightweight and straightforward, only what you really need for appengine with no restrictions to IDE - you can use any one with groovy/gae support, no need to install special heavy environment like STS. Performance seems not much worse comparing with Spring MVC
