TypeName property of ObjectDataSource 'ObjectDataSource1' could not be found

Ok, this is really frustrating...

* Using VS 2005 and an Oracle database.
1. Add a new "Report" to a reports folder in my website.
2. Click the Web Data Sources and add a new data source
3. Go through the wizard and enter my sql.  I choose only a GetData method.
4. Navigate back to the report designer, click the menu item Reports-Data Sources.
5. Add DataSet1_DataTable1 to the report.
6. Add a list control to the report design and relevant controls to be displayed.
7. Add a new web form to the reports folder and add the reportviewer control.
8. Click the smart tag for the reportviewer control and choose the report I just created.
9. The default ObjectDataSource1 is automatically added.
10. The TypeName property for ObjectDataSource1 is automatically assigned to "DataSet1TableAdapters.DataTable1TableAdapter".
11. Run the application.

Receive the following error:

 An error has occurred during report processing.
