I did. The primitive did not fail actually. In the middle of the workspace  
code I pasted, if you uncomment the #inspect call. You will find that the  
list element is properly converted. But the #inspect at the last line  
after committing shows that the list has not been updated in the database.  
I was guessing that I might be the GOODS client code?
