I'm assuming you've written some code that issues the display request.

Place the call for the display request in a try/catch structure.

Make HttpUnhandledException one of the catch clauses.

This exception should define sub fields such as a more detailed
message and exactly where it occured. You can display these to get
more details.

From reading your stack trace, it looks like you are passing an
invalid GUID to something. CRM uses GUIDs extensively for its record
keys, so it maybe that you are populating a key field on your request
incorrectly

Andy,

I get this error with the following request url in IE:

http://perfectv-mcjywm:5555/GemeenteRommeldam/_root/homepage.aspx?etc=10036

With one of the standard entity id's this works fine.
I get the same result if I add a subarea in my sitemap for this entity en
click the entityname in the menu.

The entity is imported in 4.0 from an export customizations done after
upgrading 3.0.

If you want to address a user defined entity, you´ll have to use

UserDefined/edit.aspx?etn=<entity name>
UserDefined/edit.aspx?etn=<entity nname>&id=<object_id>

Hope this helps to correct your code.
