Customizations JSP; advise needed

Question

To implement the following I hope to get some advise.
I will first explain the case:
2 tables: ARTICLES and ORDER_LINES
ARTICLES
========
id (PK)
code (UK)
description
price
vat%
vat
ORDER_LINES
===========
order_id
line
article_id
amount
price
vat%
vat
As you can see the columns price, vat% and vat are also included in the ORDER_LINES table.
This is done because the values can be different then the default values (in the ARTICLES table).
In the order line JSP page I'd like to display the
Article code, description, amount, price, vat% and vat.
The code, description, price, vat% and vat MUST be entered by invoking a LOV on the Articles.
The price, vat% and vat can be changed after invkoing the LOV
The problem is I don't know how to give back more than 1 value with a JHeadstart LOV!
How can I solve this problem best?

Answer 1

There are a few stept involved.
1 To be able to pass a comma delimited list of items you are interested in, you need to change the lovPopup.jsp to take an extra parameter, e.g. <bean:parameter id="lovDescriptorAttributeNames" name="lovDescriptorAttributes" value=""/>
2 Modify the JavaScript function jspLovPopup to take this as a (string) parameter. In this function you use this string to find the items in the calling form and put pointers to these items in a global variable.
3 Change the lovSearchResults.jsp page to take a comma delimited list of values as a parameter.
4 Modify the JavaScript function chooseLovValue to take this as a (string) parameter. In this function you copy these values to the items in the global variable with pointers.
