Hi Chand,
As far as I understand your question. Your application has an
entity called ITEM, which has 2 attributes one is CODE for the ITEM and
another is NAME for the ITEM. Now in the screen you wanted to display
one attribute (i.e. the CODE of the ITEM or the NAME of the ITEM) where
as after submission inside the ACTION class you want both the
information i.e. the CODE and the NAME of the ITEM.
Here are the possible solutions.
1) As everyone in the mailing list who has replied prior to me you can
STORE the Data object which you created while displaying the ITEM
information in the JSP page in the session. And display only CODE of the
ITEM in the page. In the session, you store the information in form of a
MAP which accepts CODE of the ITEM as the Key and NAME of the ITEM as
the value. Now when the jsp page is submitted, you would anyways get the
selected ITEM's CODE. With the CODE value you can retrieve the NAME of
the ITEM in the Action class since you already have that information in
the session object.
2) Secondly if you don't want to store the data object in the session.
And you want the information in the form of hidden fields One simple
and straight forward way is you can store all the ITEM's information
lets say the CODE and NAME as hidden attributes.
<logic:iterate id="rows" name="APPROPRIATE BEAN NAME" property="PROPERTY
NAME" indexId="i">
<input type="hidden" name="items[<bean:write name='i' />].name"
value="<bean:write name='ItemType' property='name' />" />
<input type="hidden" name="items[<bean:write name='i' />].code"
value="<bean:write name='ItemType' property='code' />" />
</logic:iterate>
After submission, you would anyway get the Selected ITEM's CODE
and you get the ITEM code and Item Name from by doing a
request.getParameter.
Or if you don't want to store all the codes as hidden attributes, here
is another way, instead of "Index I" try to store the name attribute
like
Items [YOUR CODE VALUE].name = YOUR NAME VALUE.
Have a Good Day!!!
Best Regards
Pal

Hi,
I think somebody already explained you that you don't need the name.
In the Action to which you forward you can loop up the name based on the
code.
But if you stick to this then you can create a hidden field called name
and
on the onChange of the dropdown list set the value of the hidden field
to
the selected name.
