Symptom

Consider the following scenario:

We have custom pages using the Data Form Web Part to display information. The main information is stored in a SharePoint custom list and a SharePoint custom document library. All of the data and the pages exist in the same sub-site.

The query string is defined as follows:

• On the details page:
  • The details page is displayed with details.aspx?ID=xx.
• In the datasource listing:
  • <ParameterBinding Name="CustomItem" Location="QueryString(ID)" DefaultValue="1"/>
• In the xslt:
  • <xsl:param name="CustomItem">1</xsl:param> 
    <xsl:variable name="Rows" select="/dsQueryResponse/Custom_Listings/Rows/Row[@ID = $CustomItem]" />

In this scenario, we receive the following error message:

w3wp.exe (0x1104)    0x1670 CMS    Publishing    8vzh
Unexpected PortalSiteMapProvider was unable to fetch current node, request URL:
/example/path/here/custom/pages/opportunitydetails.aspx, message: No item exists at http://SERVER/example/path/here/custom/pages/opportunitydetails.aspx?ID=20. It may have been deleted or renamed by another user., stack trace: at Microsoft.SharePoint.SPContext.get_Item() at Microsoft.SharePoint.SPContext.get_ListItem() at Microsoft.SharePoint.Publishing.Navigation.PortalSiteMapProvider.get_CurrentNode()

Cause

When we try passing the Query Parameter Name as ID to the .aspx Page (which itself is the record in the document library) Sharepoint loses track of what ID is used for. Sharepoint no longer knows if ID is the document in the document library or the ID of the listItem which we need to update using this .aspx page. This problem happens because Sharepoint has its own variable named ID which it uses to identify documents/pages on the server. Our solution should not be using a variable named ID.

Resolution

Change the query string parameter from ID to CustomID. Then change the details page from QueryString(ID) to QueryString(CustomID). Once this is done the page will display with no errors.
