logic with tiles

[Dan Allen <da...@mojavelinux.com>]

At times I want to do logic with my tile params.  For instance, on a
page I might have a tiles param for "quote", so my tiles def might
have

<tiles:put name="quote" value=""/>

I would like to do something like

<c:set var="quote"><tiles:getAsString name="quote" ignore="true"/></c:set>
<c:if test="${not empty quote}">
    <tiles:getAsString name="quote"/>
</c:if>

However, there seems to be no way to get the tiles attributes in the
jstl tags, so it requires the extra step of bringing the tile
parameter into a variable.  I know I could use

<tiles:importAttribute name="quote" ignore="true"/>

but then I would not be setting a page variable if it doesn't exist,
which is why I wrap the call in the c:set

Is there an easier way to do this I am not seeing?

Dan
