Hi David, Evidently, I didn't force a project rebuild.
Your suggestion worked. So, thank you very much!! I"m not a java/GWT expert but I am puzzled why this apparently new step became necessary for me as part of the migration from GWT 2.2 to GWT 2.4. My app had been working just fine under the older GWT version for many months. Thanks again!!!!
