Have Submit documentation explicitly state when the disabled attribute is
evaluated
-----------------------------------------------------------------------------------
Key: TAP5-1628
URL: https://issues.apache.org/jira/browse/TAP5-1628
Project: Tapestry 5
Issue Type: Improvement
Components: documentation
Affects Versions: 5.3
Reporter: Steve Eynon
Priority: Trivial
The "disabled" attribute for a Submit button is currently loosely
documented as :
" ... Further, a disabled field ignores any value in the request when
the form is submitted."
http://tapestry.apache.org/5.3/apidocs/org/apache/tapestry5/corelib/components/Submit.html
I would like it to be more explicit, along the lines of:
" ... Further, if bound, the disabled attribute is re-evaluated upon
form submission and the "selected" event is only fired should it
evaluate to 'false'."
For this stumped us in work today for a good half hour - it was
because we weren't @Persist'ing our disabled attribute. Our expression
was t:disabled="!myObject" and of course 'myObject' because null /
false on form submission. As our submit button was enabled and the
form submitted, we saw no reason for the event not to fire.
