Hi Guys

I am busy trying to upgrade our GWT project to use the 1.1.0 release
and got this error. Our code was working perfectly with 1.0.21.

Anyone know how to work around this?

I am about to start the tedious process of commenting out sections of
our 13k lines of client code to isolate the problem :(

Cheers

If my calculations are correct, you have a for statement somewhere with
a missing test expression. Something like:

for (int i = 0; ; ++i) {
}

I'll get this fix into the next release.

Thanks,
Scott

Thanks for the quick response!

Yep putting in a "true" instead of the empty tests solved the problem!
