Compiler Error

[v123]

Getting a compiler Error - it does not even name the class that it
cannot compile. Any ideas? Any known issues with maybe inner classes or
something else?

If you run the compiler with the debugging option (can't remember the
name) to "ALL", you should be able to see what file is causing this
problem.

Another suggestion is to "clean" your project but either running "Clean
project" in eclipse or manually deleting everything in your bin
directory. Sometimes the class files get out of sync.

Thanks,
Eric

Hi v123,

What version of GWT are you using? Your stack trace looks similar to
a bug that was fixed in 1.1.10.

Thanks,
Scott

[v123]

This is 1.1.0

The following is the end of the output with -ALL flag. It tries to
rebind the Sample and fails somewhere. I have only 1 inner class in
Sample, so most likely it is somewhere else, but the compiler does not
tell me where.

[ERROR] Build failed

[v123]

With v1.1.10 the assignment statement does not return a value. It
returns void.

[Scott Blum]

Hi v123,

Could you try compiling with 1.1.10?

Thanks,
Scott
