August 10, 2010The improvements in IDEA X look already great to me, especially the improved GWT support. Since GWT 2.1 will feature some major enhancements within the GWT framework: will IDEA X support some or all of these features for example the MVP infrastructure, RequestFactory etc. ? I’m thinking of the currently available commands that allows one to create remote services etc.
