Sorry to say this, i had been very impressed by the simplicity and effectiveness of puremvc for Flex development, we were waiting for this release to align gwt/flex development on similar lines. We cannot wait any longer for this to be a reality , bye for now to puremvc, we are planning to write a puremvc like framework implementation in GWT.
Anyway keep up the great work and thanks for the lightweight framework in AS3.
Best Regards,
Hafiz
