Hi.

1) I created a MM Web Forms application WebApp with the foolowing file structure:

++InetPub
+++++++++wwwroot
++++++++++++++++WebApp <- config.web
++++++++++++++++++++++ bin

It contains a Web Form that can be reached at http://ServerName/WebApp/WebForm.aspx
In this Web Form Data gets called from an access database into a datagrid that contains
an URL column that points to another Editing Web Form.

Everything works fine.

2) Now I want this application to fit into the following structure

++++++OtherVirtualDirectory <- config.web
++++++++++++++++++++++++ bin
++++++++++++++++++++++++ WebApp

I copied the files (aspcx files) to the new WebApp folder under the OtherVirtualDirectory, the Dll's to the bin folder under the OtherVirtualDirectory and I copied the config.web to the OtherVirtualDirectory.


When I hit http://ServerName/OtherVirtualDirectory/WebApp/WebForm.aspx, I get the following error:

Object reference not set to an instance of an object.


Stack Trace:

Apparently the error occurs when the businessobject asks the mmAppBase.Factory to return a dataset.

Has anyone an idea what this could be?
Thanks in advance.
