[Haskell-cafe] IO and Wash

I'm trying out WASH for a project. It looks nice, but I/O looks tricky. I have a database lookup, and I want to present each row as an option for the user. Page 15 of the Wash user-manual.pdf has an example of using the abstract table to do this. It works fine, but... if a user hits the submit button without selecting anything, they get a JavaScript message saying validation fails. Good, that's what I want to happen. But when Wash tries to re-display the current form, all the data from the database is rendered empty. I am using the example code almost verbatim. Any ideas? Thanks, John
