Subject [jira] Commented: (TAP5-520) Regexp validator parse error
Date Thu, 19 Feb 2009 22:18:02 GMT

    [ https://issues.apache.org/jira/browse/TAP5-520?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12675156#action_12675156

Mike D Pilsbury commented on TAP5-520:
--------------------------------------

I meant to create a bug for this a couple of months ago but forgot, so I'm glad that someone
else has encountered it.

Even if it could be worked around in this particular regex, I think that the restriction still
needs to be addressed; it's not always going to be easy to work around. Perhaps a comma in
the regex could be allowed to be escaped in some way?
