I've just encountered this issue during my 2.4 upgrade and have found the source of the problem, or at least in my case. I have gwt- incubator-20101117-r1766 on my classpath also, and both this plus the gwt-dev jar include classes from the flute CSS parsing library. The incubator jar was higher on my classpath, so its version was being picked up first and causing the problem.
The issue below confirms that the gwt-dev jar uses a modified version of flute that allows underscores in @def names (and other places too?), so letting the classloader find the incubator's version of flute the prevents the OPACITY_DURATION definition from being parsed properly. I guess this could have been a problem with pre-2.4 too, and maybe I've just been lucky enough to never have used any widgets that have an underscore in thier CSS @defs. http://code.google.com/p/google-web-toolkit/issues/detail?id=3946 Anyways, this thread is a little old so maybe this post is too late, but hopefully it can help someone else in the future. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
