You can't nest custom tags in the attribute values of custom tags.
If you instead used the Struts-EL library (check "contrib/struts-el" in Struts
distribution), your excerpt would look like this:
<html-el:form action="/choice" name="choiceForm"
type="carl.struts.ChoiceForm" >
<html-el:select property="topic">
<c:forEach items="${subjects}" var="subj">
<html-el:option value="${subj}"/>
</c:forEach>
</html-el:select>
<html-el:submit>Choose Subject</html-el:submit>
</html-el:form>
This might be better if you could use the "options" or "optionsCollection"
tags, instead of iterating through a collection and explicitly creating
"option" tags. However, this may have a wrinkle, as I believe those two assume
the collection is a collection of beans, not strings, as I think you have here.
