Hal E. Louya! - I went to Properties->Project Facets and changed it from 1.4 to 1.7 as you said and it compiled 6 permutations without errors. It took a very long time and the way the window went blank for a long time I thought I might have broken Eclipse.
I looked at the Runtimes tab. Neither App Engine nor Java was checked but it did show jdk1.7 Now, I've got to see If the demo app actually runs. I'm not confident but maybe I'll be lucky. Thanks again for the help, Michael. ...Bob -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
