No, but there are workarounds: http://code.google.com/webtoolkit/doc/latest/FAQ_DebuggingAndCompiling.html#Can_I_speed_up_the_GWT_compiler?
(note that setting user.agent or a single locale won't speed up the DevMode, but they are honored anyway, so this can be used to set devmode-only properties: you'll have a "dev" module and a "prod" module, instead of the suggested "firefox" and "all browsers" module; FYI, this is what Apache Wave uses to optimize the compiled code for production but have as much debug info as possible when developping) -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
