Subject [jira] Commented: (WW-2732) <s:text name="key"/> OGNL-evaluates "key" when it is not found in resource bundle
Date Wed, 17 Dec 2008 23:04:36 GMT

    [ https://issues.apache.org/struts/browse/WW-2732?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=45305#action_45305

Kevin Biesbrock commented on WW-2732:
-------------------------------------

And searching the resources file could return something other than title (e.g., in the case
of I18N)?  Is that what I'm missing?

> <s:text name="key"/> outputs the resource message designated by "key".
> If no such message exists (and the body of the tag is empty), it reverts to outputting
the name of the key itself, as an unevaluated string.  At least, that's the behaviour of the
tag, as described in the documentation.
> In fact, however, the name of the key is now being evaluated as an OGNL expression, and
if that turns out to be valid, that is what's printed.
> This, in my view, is counter-intuitive and probably counter-productive.  Consider the
case of a ModelDriven<Book> action exposing a Book-object to the View.
> Normally,
>      <s:text name="title"/>: ${title}
> would have yielded:
>     title: The Great Gatsby
> if the resource message "title" was missing from the resource bundle.  That's not too
bad an outcome.  However, with the key being OGNL-evaluated, we would get the following output:
>     The Great Gatsby: The Great Gatsby
> which I find a little puzzling...
