By the way, yes you can get your servlet engine to GZIP your responses. You
can use a servlet filter for that...

What are the types of the objects in the UserDataForm.names collection? The
error message is telling you that you're trying to access the "lastName"
property on an object of type String, which of course is not there.

I just took a look at my tomcat log and I am getting this error (should
of looked here a long time ago :-) )
org.apache.jasper.JasperException: An error occurred while evaluating
custom action attribute "value" with value "${userData.lastName}":
Unable to find a value for "lastName" in object of class
"java.lang.String" using operator "." (null)
Not sure what that exactly means, I will have to investigate more...

Brian;
Could there be something in your data simulating html injection? IE,
could you have a
character(s) in your data that could be interpereted by the browser as
an html tag?
