I'm still stumbling on some details.
For
<logic:iterate id="feature" name="features">
<tr>
<td>
<c:choose>
<c:when test="${feature.premium == true}">
<c:out value="true"/>
</c:when>
<c:otherwise>
<c:out value="false"/>
</c:otherwise>
</c:choose>
</td>
</tr>
</logic:iterate>
fwiw, "features" is put in the request scope using
request.setAttribute("features", features);
in the Action that provides data to this JSP view.
The JSP prints false for cases where I know feature.isPremium() is true.
I suspect the 'feature' scripting variable has different meanings in the
two ways in which it is being used (logic:iterate tag and c:choose tag)
Help is appreciated, and I'm on my way to get modern books on both Struts
and JSPs.
