[jira] [Commented] (WW-3478) Allow exceptions to be thrown from the validate() method

["Tom Terrace (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WW-3478?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13044890#comment-13044890 ] 

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!).

> 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.
