could not resolve view with name '' in servlet with name

[aleks_sh]

Hello All
After upgrade from 3.4d to 4.0b do not working site's dashboard.
When i click on site name in "My sites" dashlet i had that error:

A server error has occured.
There are a number of reasons why this could have happened:

    You have attempted to access a page that does not exist - check the URL in the address bar.
    You have attempted to access a page that is not accessable to you, such as a private Site dashboard.
    A valid page has been requested but the server was unable to render it due to an internal error - contact your administrator.

Return to your dashboard page

in catalina.out i see:
