How to use nested tag in Struts

Question

Hi..
Can any one guide me how to use nested tag in Struts. So far i already tried bean tag with no error but when i try to use nested tag i got error like
javax.servlet.ServletException: Cannot find bean: "" in any scope
Below are my class:
action class
session.setAttribute ("MyDetailList", detailList);
JSP page
<logic:iterate id="list" name="MyDetailList">
Company ID : <bean:write name="list" property="companyID" />
</logic:iterate>
For bean tag, i got no error at all and below are my code for nested tag
action class
session.setAttribute ("MyDetailList", detailList);
JSP Page
<nested:nest property="MyDetailList">
Make : <nested:text property="make"/>
Car ID : <nested:text property="carID"/>
</nested:nest>
When i run the code, i got error message
javax.servlet.ServletException: Cannot find bean: "" in any scope
Any body can help me?

what am I doing wrong?You will notice above that I mentioned
YOU CAN'T USE CUSTOM TAGS AS ATTRIBUTES TO OTHER CUSTOM TAGS
(was that loud enough for you to notice this time)?
Try
<html:text styleId="instruction" styleClass="text" size="50" name="instruction" property="value"/>
//or
<html:text styleId="instruction" styleClass="text" size="50" property="instruction" value="<%= instruction.getValue() %>"/>
better alternative: populate your formbean with your action and just have:
<html:text styleId="instruction" styleClass="text" size="50" property="instruction"/>
If you set the "instruction" property of your formBean in the action, the value will be automagically reflected here.
