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
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?
