We ran into the same problem. We took a different approach particular to the function no longer being supported.
The DOM.gwt.xml switches user.agents with ie10 or less from StyleInjectorImpl to StyleInjectorImplIE. In the gwt.xml file we check if the function exists return typeof $doc.createStyleSheet === 'function'; If that function does not exist and the user.agent is ie10 or less switch StyleInjectorImpl to IeCompatibilityStyleInjectorImpl. IeCompatibilityStyleInjectorImpl is a class we created that just extends StyleInjectorImpl. This was required so that the DOM.gwt.xml doesn't find and try to switch StyleInjectorImpl. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
