I've tried both 10762 and 10781 and in both builds, when I a) open an existing project or b) create a new project from existing sources, in both cases, the Grails/Groovy facet no longer exists. As such I am unable to specify the Grails SDK anywhere.
Is this expected behaviour i.e. has this functionality moved to some other part of IDEA? Furthermore, none of the grails-app folders are marked as source folders. All seems very broken. Anybody else seeing this behaviour?
