collections and populating them
Hi
On my JSP page I display the results of Database query
like this:
(mapKJ is in request)
<html:select property="ko_id">
<html:option
value="">--select--</html:option>
<bean:define id="map" name="mapKJ"/>
<html:options collection="map"
property="key" labelProperty="value"/>
</html:select>
and here some other <html:text .......> fields.
The point is that when I validate other text fields and I get back to the
same
JSP page but my collection disapears. And I get an error "Cannot find mapKJx
in
scope request".
My questions are:
Why do I get back to the same page with an error -like above- when
validation fails? (in this case I can't execute any code to get data from
the data base - why is that?)
What happens to my mapKJx collection, ?
Thanks in advance.
Chris

Using VO factory pattern in Struts Action class?
Posted by Leon <le...@hotmail.com>.
Hi,
VOs are glue through presentation, business and data tiers and Action class
has resposibilities to convert a FormBean to a VO. Should I implemente a VO
factory pattern and let Action class find a VO in order for decoupling
between client and implementation calsses?
Any suggestion?

I have a similar issue, but I don't know how to
retrieve the selected itens in a multiple select
option field submitted by the user submitted and the
page should be shown back with an error.
Please, image that the collection is session scoped,
how are the itens of the list shown when the page gets
back to, I mean, which will itens be shown selected?
Thanks for any help!

I had an exact same issue and I overcame it in couple of different ways
(depending on the case):
1st: If a collection is used across the application (States, countries)
store it in the context
2nd: Otherwise set the input page in the struts-config to the setup
action, not the jsp
(IE if you have a submit.jsp and a preSubmit.do, then input should be
preSubmit.do)
That way, when the validation fails, it goes back to the setup action
and prepopulates the form.
Otherwise you have to store it in the session, because... Well, others
explained that part already.
