There was a topic on this forum, about a year ago, about bringing Spring (3) integration into Seam 3, but I haven't seen any news since then. Is this idea going to be realized?
It's definitely a module we'd like to see explored. We are looking for a community member interested in working on this integration. The Seam team is primarily made up of of community members (1:4 ratio), so you'll be in good company. Join us in seam-dev chat.
We can help get the module setup once we have some prototype code to seed it.
