I come across some problems in Reporting Services 2005 in SharePoint integration mode when using Navigation – Jump to URL. Here are some strange behaviors on the problem:
1. The link won’t work if you link to a page/item inside a SharePoint List.
2. The link is OK if you link to invalid page/item in a SharePoint List (invalid item name but valid path)
3. The link is OK if you link to other site like http://www.microsoft.com or http://www.ajaxworkspace.com
