@Validate(required=true) still throws an NPE
--------------------------------------------
Key: STS-718
URL: http://www.stripesframework.org/jira/browse/STS-718
Project: Stripes
Issue Type: Sub-task
Components: Validation
Affects Versions: Release 1.5.2, Release 1.6
Environment: Ubuntu 9.04, Sun Java 1.6.0_16
Reporter: Marcus Kraßmann
Priority: Minor
Although the sourcePage is now correct, an NullPointerException is thrown if
the validation error's cause is a @Validate annotation. Although this fails,
validation errors that are added in ValidationMethods work fine.
Stacktrace, based on the previous linked Eclipse Dynamic Web Project
"Form-Behaviour" after i did not fill in anything in any field:
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
HTTP Status 500 -
type Exception report

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Tested with current subversion trunk and 1.5.x branch. Priority set to minor
because using validation methods is an acceptable workaround.
