Vaddin spring-security redirect error

I am working on Vaadin spring-security SAML authentication system. The problem is - when user goes to vaadin app address (if it is not authenticated) it has to be redirected to IDP login page. But in place of this redirection (the address changes in address bar) I got an error: Failed to load the widgetset: /my_vaadin_app/VAADIN/widgetsets/com.vaadin.terminal.gwt.DefaultWidgetSet/com.vaadin.terminal.gwt.DefaultWidgetSet.nocache.js?1359109584453

Does any one has suggestions why such thing happens. I read that vaadin does only some kind of internal redirects and does not understand external redirects.

I’m facing with the same problem. Anyone knows implementations of the Spring SAML extention with Vaadin 6.

Thanks.
