Re: Does the GWT "magic" ever fail you?

@Samyem -- Good point about the async RPC...we also had that issue
when debugging and/or integration testing Flex/Actionscript.

@Jeff -- Your metaphore is correct...to continue it, I'd say I trust
my Java/C++/C# compilers a lot. My concern is exactly whether or not
the GWT compiler has issues. Do you disable optimizations during
development or is that for production code too?

@Thomas - Sourcemap is incredible if it works as advertised....is
that how Eclipse keeps the Java debugger "in sync" with the browser
Javascript execution?

Thanks everyone for your answers.
