> Project: Tapestry
> Issue Type: New Feature

> Fix For: 5.0.14

>
> Same idea as in Tapestry-2541 but in a much lighter way :
> In my case, I use the Layout pattern for rendering my pages, but depending on
> the situation, sometimes the body of the layout is empty. In that case I
> would like to display a generic content. So I imagine something like this :
> <t:if test="hasBody">
> Blah blah blah
> <t:parameter name="else">
> <t:body />
> </t:parameter>
> </t:if>
> But I don't know how to write the test "hasBody".
