Thanks Antonio,
I think I was just feeling a little insecure about the code I was
writing. Ultimately, I just want to make sure that I'm doing things
the right way. If using JSTL falls within the scope of best practices
for pulling out putList attribute values, I'm satisfied.
To answer your question, I didn't like the approach because I managed
to build most of my application without the Core JSTL (using the
Struts tags with OGNL support instead). Introducing another taglib
just felt wrong. For some reason, the tests I did using the "iterate"
tag didn't work -- probably because I don't fully grasp the OGNL
syntax yet.
Conclusion: Looping over the attribute sent in from the named putList
is the right way to pull values out. If using the JSTL Core "forEach"
tag is acceptable, I'm satisfied. However, I'll be more satisfied
when I can get it to work with the struts "iterate" tag.
Thanks again,
Eric Rank

Hi all,
I am trying to insert items from a putList defined in my tiles.xml
file in a template file. The only way that I can seem to do it is
by using the following process
1. make the putList 'List' accessible on the page with
<tiles:useAttribute name="myPutList" />
2. sending that variable in to a JSTL Core taglib forEach loop
3. using <tiles:insertDefinition name="${putListItem}" />
I think your code is perfect, so why don't you like it?
Tiles 2 does not depend on Struts anymore, so the "best practice"
is to use the most generic tag libraries, that is JSTL.
Instead of <tiles:useAttribute> you can use <tiles:importAttribute>
that does not create a scripting variable, but only a page context
attribute.
Anyway you can use all the "iterate" tags you like.
