Getting the value of a field is a runtime operation, and a generator runs at compile-time. The only thing you can do is generate code that will read the field's value and act upon it at runtime, and then hope for the compiler to possibly detect that the value is actually constant and thus optimize out all the code you generated that would never be reached. Put differently, imagine the generator runs right within Eclipse (or your IDE of choice) and generates *.java files. This is more or less what happens actually, except internally during the compilation. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
