[web2py] SQLFORM boolean fields edit problem

[Cliff]

SQLFORM appears to not correctly display the value of an updated
boolean field after submission.  Text fields correctly show updated
values.

In the toy application below, if you edit a dog record and update one
of the boolean fields, you will find it unchanged after a submit.  If
you edit the text field and submit the form, you will find the text
field changed.

The problem goes away if you add a redirect after the
form.accept(...), like this:
redirect(URL('edit', args=request.args(0)))

Here is the application.  If anyone finds something that would cause
this behavior, please let me know.

Thanks,
Cliff Kachinske
