IE Compatibility Problem?

I read the GWT are not compliant with IE 7 - 8 is It true? If is true VAADIN will not work??

It should be a problem.

GWT supports IE6-IE8 (http://code.google.com/webtoolkit/doc/latest/FAQ_GettingStarted.html#What_browsers_does_GWT_support?) and so does Vaadin (http://vaadin.com/features)

Thank a lot for the quick answer!!! :)

However, take a note that Google has stopped support for IE6 - thus, future versions of GWT may not be 100% compatible with it as well as Vaadin in some far future.
