Enclosure with fallback section
-------------------------------
Key: WICKET-1937
URL: https://issues.apache.org/jira/browse/WICKET-1937
Project: Wicket
Issue Type: Wish
Components: wicket
Reporter: Peter Parson
Priority: Minor
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>
