Hello Ramón,
   Thank you for answering.   Unfortunately the "MADescriptionBuilder
default flush" did not change my problem.
   DatabaseTable>>fieldNamed: is still called with 'detailUrl' which
does not exist as an attribute, method or description.
   I am attaching a SqueakDebug.log so may be you can see something that I dont.
   Thank you very much
