The Value of a Property in a Drop-Down Menu

[Caroline Jen <ji...@yahoo.com>]

My Collection, PageBeans (plural), generates a
drop-down list like this:

<html-el:select property="document">
<html-el:option value="">-Select-</html-el:option>
<html-el:options collection="PageBeans"
property="name" labelProperty="name"/>
</html-el:select>

Each individual bean, PageBean (singular), in the
Collection has two properties; name and groupID.  I
want to display 'name' in the drop down list. 
However, I want the 'value' of 'groupID' to be
submitted when users click on the Submit button.

Therefore, the statement in the servlet:

String selected = request.getParameter( "document" ); 

picks up the value of the 'groupID' instead.  Do I
change the generation of the drop-down menu:

<html-el:select property="document">
<html-el:option value="">-Select-</html-el:option>
<html-el:options collection="PageBeans"
property="groupID" labelProperty="name"/>
</html-el:select>

Yes, that should work - "property" holds the values that will be passed 
with the form, and "labelProperty" holds the labels that will be seen by 
the user.
