I've a strange question for you. I have to fix bugs in the another's code (webpart for sharepoint 2010). So in the code there is a line with the code below:

  var s = (String)((PersonalWebPartPage)Page).Profile["AccountName"][0];

and then I tried to view next error appears:

Unable to cast object of type 'ASP._layouts_wpprevw_aspx' to type 'Microsoft.SharePoint.Portal.WebControls.PersonalWebPartPage'.  

But this code somehow working on the corporate portal. What it can be? =) Or maybe I've missing some references?

Many kinds of pages can have Web Parts in them. Make sure that the actual page where the Web Part is deployed inherits from Microsoft.SharePoint.Portal.WebControls.PersonalWebPartPage.

Look for something like this:

<%@ Page Inherits="Microsoft.SharePoint.SharePoint.Portal.WebControls.PersonalWebPartPage,Microsoft.SharePoint,Version=14.0.0.0,Culture=neutral,PublicKeyToken=71e9bce111e9429c" %>
