Do not display errors or errored field decoration on form refresh
-----------------------------------------------------------------
Key: TAPESTRY-867
URL: http://issues.apache.org/jira/browse/TAPESTRY-867
Project: Tapestry
Type: Improvement
Components: Framework
Versions: 4.0
Environment: Tapestry 4.0, Tomcat 5.5.9
Reporter: Ben Dotte
This is related to TAPESTRY-636. When a form's refresh listener is called,
client-side validation is bypassed but server-side errors still show up. This
becomes a problem if you want to refresh a form but not show any errors.
Calling clearErrors() on the validation delegate does get rid of the error
messages but it also clears any invalid data entered by the user, which is an
unwanted side-affect. While onsite, Howard suggested a fix where errors kept in
the validation delegate and errored field decoration would be switched off if
the form's refresh listener was called. This would make the refresh listener on
Form much more useful. One undesired side-affect might be that if errors are
already displayed on the page from a previous form submission and the user does
something to refresh the form, the errors would disappear.
USE CASE: The user is filling out a self profile beginning with name and
address, mistakenly enters '12e45' for the zip code, and then uploads a photo
which automatically refreshes the form for a preview. Errors are displayed
about the zip code and the remaining required fields which haven't been filled
in only because the user hasn't gotten to them yet. Calling clearErrors() would
get rid of the errors, but it would also clear the zip code entered by the
user. Ideally, the form should maintain all input and not display any errors
during this form refresh.
