I'm confused. Like Joe, I haven't found much use for the lists, but I
thought that the different between add and put was basically that the
add added a value directly to a list while the put added a new
Attribute. I kind of equated it to a list and a map.
If you rename it to putAttribute, then it will be identical to the
refactor above. In essence aren't you removing this tag instead of
renaming it?
Yeah, in fact now I am thinking to rename it to "putAttributeValue".
Moreover, the <add> element's name is not required, but <put> is.
Actually, there is no "name" in add. That's the entire difference
between the two. It separates a simple value in a list from a named
attribute - right? Because it's not a name/value pair, I think I like
add better than put.
Values are still stored by <item> and <bean> (this

?
Don't worry, I was mistaken myself...

Can you explain the use case more? I don't see how we can insert an
attribute which hasn't been named.
A ComponentListAttribute is, in fact, a list of ComponentAttribute,
whose name is not used at all.
It is useful if you have some sort of "dynamic layout", such as a list
of attributes one under another.
For example, in the "vboxLayout.jsp" pages in the showcase there is
(now) the following snippet:
#SNIP#
<tiles:useAttribute id="list" name="list" classname="java.util.List" />
<%-- Iterate over names.
We don't use <iterate> tag because it doesn't allow insert (in JSP1.1)
--%>
<c:forEach var="item" items="${list}">
<tiles:insertAttribute value="${item}" flush="true" />
<br>
</c:forEach>
Gotcha. Thanks for the clarification. I hadn't considered that . .
.The change works for me.

What it does is putting a definition or a template in those places.
