Html:link action html:link on results page null

Question

I am sure that this is something simple and small but I have been banging my head against this problem for a while now.
I am using the <html:link> tag on my index.jsp page activates an action, retrieves a result and forwards to the homePage.jsp. The home page has a tiles layout and the results are actually in homePage_lowerLeftLevel.jsp within the homePage.jsp. Below the results I have an <html:link> tag which is identical to the tag in the index.jsp but now instead of seeing the link there is [ServletException in:/pages/homePage_leftLowerLevel.jsp] null' and if I go back to the index.jsp I get the following error�
java.lang.NullPointerException

If this <html:link> tag is not on the results page the results display perfectly. Here is my code:
********index.jsp**************
<%@ page language="java" %>

<html:link page="/homePage.do?areaId=bcId">Click Me </html:link>

Thank you very much for your help

It should be used something like this!!!
<html:link action="myStrutsAction" paramId="user" paramName="userName"/>if the userName attribute had the value "Bob" that would produce:
