Subject [jira] [Commented] (WW-3850) NullPointerException loading xwork validator since 2.3.4
Date Mon, 20 Jan 2014 07:23:22 GMT

    [ https://issues.apache.org/jira/browse/WW-3850?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13876207#comment-13876207
] 

Sanket Meghani commented on WW-3850:
------------------------------------

By validators I mean, validation rules defined for a field in <Action Class>-validation.xml.
I think what it is trying to do is get a list of validations defined for a field in <Action
Class>-validation.xml and apply it manually. Which I think is not needed at all, the framework
should do it automatically as long as I understand.
