Tapestry should not persist error messages during XHR requests
--------------------------------------------------------------
Key: TAPESTRY-2784
URL: https://issues.apache.org/jira/browse/TAPESTRY-2784
Project: Tapestry
Issue Type: Bug
Components: Core Components
Reporter: Ville Virtanen
Priority: Minor
Tapestry persists the error messages that result from form validation to
support the post redirect get paradigm, which is correct and expected behavior.
However, this is not the correct nor most efficient way to handle things during
AJAX requests, as the response is rendered out during the same request.
This was discussed with Thiago on the mailing list:
http://tapestry.1045711.n5.nabble.com/T5-3-rc-3-Error-messages-and-AJAX-td4974222.html
I dont see any side effects of this, but the least that must be done is to
prevent the persistence when the errors are red during the same request. Now
the errors are present on subsequent request too (shown twice).
