["Jochen Kemnade (JIRA)" <ji...@apache.org>]

Jochen Kemnade updated TAP5-1160:
---------------------------------

    Labels: bulk-close-candidate  (was: )

This issue has been last updated about 1.5 years ago, has no assignee, affects an old version of Tapestry that is not actively developed anymore, and is therefore prone to be bulk-closed in the near future.

If the issue still persists with the most recent development preview of Tapestry (5.4-beta-6, which is available from Maven Central), please update it as soon as possible. In the case of a feature request, please discuss it with the Tapestry developer community on the dev@tapestry.apache.org mailing list first.

> Ternary is if-then-else:
> expression ? if-true : if-false
> That is evaluate expression, then evaluate one of the two other expression (if-true and if-false)
> "Elvis" is the nickname of a similar operator in Groovy:
> expression ?: if-false
> which is equivalent to
> expression ? expression : if-false
