jsp:param & nested tag & null

[ZC...@tsys.com]

struts v1.1
jsp v1.2

When I pass a jsp:param to a dynamic include and try to read the parameter 
in a nested:equal I get a 'null' error message. When I change the tag to a 
logic:equal it seems to work. I'm just trying to understand why this is 
happening?

***** Main.jsp *****
<nested:iterate property="myList">
...other code...
        <jsp:include page="MyInc.jsp">
                <jsp:param name="useHeading" value="true" />
        </jsp:include>
</nested:iterate>

***** MyInc.jsp *****
<nested:root>
        <nested:equal property="showTasks" value="-">
        <table width="100%">
                <!-- need to use logic tag for the jsp:param passed in, the nested tag 
produces null -->
                <logic:equal parameter="useHeading" value="true">
                <tr>
                        <th width="20">&nbsp;</th>
                        <th><bean:message key="label.head1" /></th>
                        <th><bean:message key="label.head2" /></th>
                </tr>
                </logic:equal>
                <tr>
                        <td>table cell data</td>
                </tr>
        </table>
        </nested:equal>
</nested:root>
 
Thanks much!
