3) Select 'General' assay radio button then 'Next' button
4) Give the assay a name, and click 'Save & Close' button
5) Go to http://localhost:8080/labkey/fermentation/Fermentation/begin.view?rowId=X
   where X should be the rowId of the assay design that was just created

The bug should result in a assertion error.
If the bug has been fixed, the main body of resulting page should be empty.
