How to use a bodytag inside an other bodytag??

Hello!

I'm trying to use an body tag from Struts inside the body in one of my own body tags.

In my mytags.tld I have specified the tag like:

    <tag>
        <name>TaskFormTag</name>
        <tagclass>attentionizer.taglib.TaskFormTag</tagclass>
        <bodycontent>JSP</bodycontent>
    </tag>

In my JSP-page I use it like:
(code snippet)
<mytags:TaskFormTag>
<table>
    <tr>
        <td></td>
    </tr>
    <tr>
        <td>
            Select task type
        </td>
        <td class="TEXT_VERDANA_BLACK_10">
       
            <html:select property="tasklist">
                <html:options collection="tasks" property="id" labelProperty="name"/>
            </html:select>
        </td>
    </tr>
</table>
</mytags:TaskFormTag>

But when I run it I get this error:
javax.servlet.jsp.JspException: ServletException in '/tiles/product.jsp': Cannot find bean under name org.apache.struts.taglib.html.BEAN
    at org.apache.struts.taglib.tiles.InsertTag$InsertHandler.doEndTag(InsertTag.java:923)


I guess it means that during the evaluation of the body of the tag the tag org.apache.struts.taglib.html.BEAN is not found.

I have also tried to add this line of code inside the body:
<%@ taglib uri="/tags/struts-html" prefix="html" %>

This line is used earlier as well in the code of the jsp-page, but I get the same error.

So if you guys could advise me how to solve it it would be great.

Best regards
