This URL should end in a ? (for plain URLs) or & (~& if using positional parameters in wc) for Querystring based URLs so that ShowCursor can add parameters on the URL after it.
For example,
PagedCustomerList.wwd?
creates: PagedCustomerList.wwd?Page=4
PagedCustomerList.wwd?CompanyFilter=a&
creates: PagedCustomerList.wwd?CompanyFilter=a&Page=10
