Parameter Passing Problem with JSP 2.0 Tag Library

[eschreiber]

I am having a problem passing a collection using a jsp 2.0 tag library.

Here is the code I am using to call the tag library.

--------------
<%@ taglib prefix="widgets" tagdir="/WEB-INF/tags/ch_widgets" %>
....

<hr>
Languages Before : [<cut value="${video.languages}"/>]
<hr>
<widgets:languages video="${video}"/> --------------

Here is the relevant part of the tag widgets:languages:

--------------
<%@ include file="/WEB-INF/tags/includes.tagf" %>
<%@ tag body-content="empty" %>
<%@ tag dynamic-attributes="attributes" %>
<%@ attribute name="video" required="true" %>

<hr>
Languages After: [<cut value="${video.languages}"/>]
<hr>
--------------


Here is the problem. The cut that prints "Languages Before" prints
out the collection of languages. The cut that prints out "Languages
After" is empty when it prints out the collection. What possibly could
have happened between the code calling the tag and the tag itself that
would make the video.languages collection empty?
Thanks for your help.
