Thanks for your response. It still doesn't work. I looked at the page
you refered me to and the HashMap is names values and the getter/setter's
are named getValue, and setValue. Is the s at the end of the map name
important.
I changed my form/jsp to work with an element of a known name.
in the form
private String foo = null;
public String getFoo ( ) {
return foo;
}
public void setFoo ( String foo ) {
this.foo = foo;
}
and the input tag becomes
<html-el:text property='${element.element}'
value='${element.value}'/>
And it works like a champ. Is there anything else I have to do
to make the HashMap work? Like use a different Base Form class?
This seems easy enough? I'm losing my mind!

In your jsp page, you have to specify your input as
<html:text property="xxx(key)"/>
where xxx maps to the map name.
