Vaadin 7 on IE9

When I use Vaadin 7 on IE9 my simple LoginForm don’t have any styles applied to it

I see that for all components. Not just the login form.

Some things to try:

  • Make sure your theme correctly inherits e.g. the “reindeer” theme (probably not an issue if works on other browsers).
  • Check that your widgetset (if you have a custom one) is compiled with the version of Vaadin you are using, and you have updated all static resources (theme, widgetset) if you have extracted any.
  • Clear the browser cache.
  • Clear server working directories (e.g. Eclipse context menu on a server has two items for clearing different temporary data).

Current Vaadin versions do pass extensive automatic tests on IE9, so this is likely to be an issue in your environment.
