On the result page I only need the Label for the selected option. Not the entire list. The problem is that when you submit the form, you only submit the value in the form object and loose the label. I need to pass the label as well so that I do not have to requery for it.
The way that i have it currently is that the value contains a comma delemited string containing both the label and key (overkill on the bandwidth I know). In my action class, I do a string.split on the comma and pass the first value to my DAO processor and the Second value I put in my form for display. It is the only way I could think of without iterating through the options or storing the initial results which populate the option list.

I'm not sure I understand... do you just need to have the group name
when you display the detail for the selected item, or do you need the
entire select list (to avoid getting it from the datavase each time?)
If you just need the grou pname, could you simply put the group name in
session? May or may not work depending on the flow of your app, but it
would be a nice, simple solution if it'll work... just remember to clear
it out at an appropriate time.
The other option that comes to mind immediately is indeed to use
_javascript_... seems like all you'd need is a form with two hidden
fields, groupName and value... onChange of the select, populate those
two fields and submit() the form. You'd then have both pieces of
information to render your detail page.
Or maybe I don't understand the problem?
