Subject [jira] Commented: (TAP5-520) Using regular expressions with the @Validate annotation causes odd parse errors if the regexp includes common characters (including commas)
Date Wed, 04 Mar 2009 23:39:56 GMT

    [ https://issues.apache.org/jira/browse/TAP5-520?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12678992#action_12678992
] 

Igor Drobiazko commented on TAP5-520:
-------------------------------------

Why "invalid" or "won't fix"? This is a bug. I have already a fix using positive and negative
lookahead. Was just thinking about test cases. Shall I commit the fix?
