Ah yea, I screwed up the example in my email, but yes, it's declared
like so:
@Parameter(required = true)
List<String> fooList;
Mind you it works for the "normal" static cases, and the case where it's
passed as a property (#1 and #2), but not inside a <t:loop>.
By any chance does your code change the value of the fooList field? The
prop binding is bidirectional so, if you change it's value, it changes the
property which was bound to that parameter too.

Just checking to be sure, but are you sure you didn't forget the
@Parameter on the fooList property in your component?

This is a strange one.
I have a Foo component that wraps a progressive display (not sure if
that part is relevant). One of the parameters to this component is a
list of strings, "t:fooList":
@Property
List<String> fooList;
In the page I'm trying to include it in, it works as expected if I set
fooList with:
1. t:fooList="list:literal:aFoo"
2. t:fooList="prop:someFooList"
But if I wrap my Foo component in a <t:loop> and try to set the fooList
that way, I get errors:
<t:loop t:source="listofFooLists" t:value="aFooList">
<t:foo t:fooList="prop:aFooList" />
</t:loop>
where those properties are:
public List<List<String>> listofFooLists(){...}
@Property
List<String> aFooList;
The specific error is an NPE in the Foo component when it tries to
access it's fooList field.
I'm not sure if being a progressiveDisplay component has anything to do
with it, but somewhere along the way the fooList is being nulled. By
printing out ${aFooList} besides mt <t:foo/> I can see that what is
being passed to the component is indeed, not null.
I'd appreciate any advice, as this is quite a stumper for me.
Cheers,
Casey
