Tom Terrace commented on WW-3478:
---------------------------------
After looking at WW-3559, I realize I may be using the validate method when I
should be using prepare. It seems much cleaner to put all the lookup calls that
could throw exceptions into prepare(), and leave the logic to populate
action/field errors in validate() as Steven said (thanks!).
> Allow exceptions to be thrown from the validate() method

> Key: WW-3478
> URL: https://issues.apache.org/jira/browse/WW-3478
> Project: Struts 2
> Issue Type: New Feature
> Components: Core Actions
> Affects Versions: 2.2.1
> Reporter: Tom Terrace
> Priority: Minor
> Attachments: validation-exception-patch.txt
>
>
> In the ValidationInterceptor, any exceptions from the validation prefix
> methods validateXXX and validateDoXXX are rethrown, but we can't throw
> anything from the plain validate() method. It would be great to just have
> one validate method that can fetch the model and throw any security or
> RecordNotFound exceptions rather than a whole bunch of identical validateXXX
> methods.
