Subject Action Tag java.lang.StackOverflowError
Date Wed, 02 Sep 2009 16:15:27 GMT
I've been banging my head against the wall for the past 6+ hours or so and 
need help with this problem.

I am trying to call an action to display results on a page when the page 
is closed, but I keep getting a loop that keeps printing the data over and 
over until a StackOverflowError occurs.

My code looks like this:

index.jsp

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>

        <head>
    <title>Action Tag</title>
        </head>

        <body>
                <h3>Action Tag</h3>
                <hr/>
                <h4>This line is before the ActionTag invokes the 
secondary action.</h4>
                <s:action name="TargetAction" executeResult="true"/>
        </body>

</html>

      return SUCCESS;
   }
}


Can anyone assist me?
