Oops! I do get the error. I was wrong when I said it worked for me. When I attempted to change the GWT version from 2.7.0 to 2.8.0 in eclipse, eclipse switched it back to 2.7.0 for reasons I cannot figure out. Given below are the offending UiBinder code, the corresponding Java code, and the stack trace when switching a running application from GWT 2.7 to 2.8. Any help would be greatly appreciated.
