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,
