> The issue resides in the JS code that is responsible for updating
> javax.faces.ViewState key in the hidden input elements.
> In IE7 during the second update the lookup for the 'javax.faces.ViewState'
> named input element fails. The element[name] syntax is used for the lookup
> which is known to fail for elements with complex names (such as
> 'javax.faces.ViewState').
> When the lookup fails to find the input element a second input element is
> created which will contain the new javax.faces.ViewState value. The next
> submit will send two 'javax.faces.ViewState' parameters but only the first
> one (the oldest) is read by the server state manager . This old key is not
> known to the server anymore and this causes a ViewExpired exception to be
> thrown on the server.
