[jira] Commented: (WICKET-1937) Enclosure with fallback section

["Juergen Donnerstag (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WICKET-1937?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12654192#action_12654192 ] 

Juergen Donnerstag commented on WICKET-1937:
--------------------------------------------

Enclosue is a rather generic component which avoids that you need to create a large number of tiny, but different, components. That doesn't seem to be true in your case. You describe it as something you need more often. Hence creating a new panel component which serves your purpose is the way to go, rather than enhancing enclosure with something that is only useful for lists.

> Enclosures would be even more useful, if a "fallback section" could be defined which is displayed only when the enclosure is not displayed.
> This way, an explanatory message like "No items in this list" or similar could be displayed quite easily.
> e.g.
> <wicket:enclosure child="someList">
> <div wicket:id="someList">
> <!--  ... markup of element someList (which sets its own visibility to false if empty)  ... -->
> </div>
> <wicket:fallback>
> Sorry - nothing to display here. <!-- this message would only appear if the list is empty -->
> </wicket:fallback>
> </wicket:enclosure>
