trying to use nested tags

Hi, all.
I have a jsp which is supposed to reflect a nested bean structure, where package object has a nested request object.
The error I get is: "Null property value for 'request'".
This is the jsp code:
<nested:form action="/Package" focus="packageNumber">
Package Number: <nested:text property="packageNumber"/>
Package Name: <nested:text property="packageName"/>
<nested:nest property="request">
TR Number: <nested:text property="requestNumber"/>
User Name: <nested:text property="userName"/>
</nested:nest>
<html:submit>Submit</html:submit>
</nested:form>

The ActionForm class has property request of type Request, for which there
is a setter a getter.
If I take the request bean out from jsp, the jsp displays fine. With the request bean in, I get the above mentioned error.
Can anyone help? Thanks in advance.

I am not a specialist in JSP, except for some dabbling, but generally this might happen if your reference is pointing to null, that is, if it has not been pointed to a request object. Since you mention nested tags, could it be that there is a valid request object, but it just isn't passed or assigned into the context of the nested tag you are calling it from?

P.S. Do you check your private messages?

It is sorta covered in the JavaRanch Style Guide.
