Re: List pages with editable data (newbie)

[Greg Blomqusit]

Martin,

I found this page searching elsewhere, since I found no help on this message
board:

http://www.manning.com/ao/readforum.html?forum=siaao&readthread=322
which references:
http://jguru.com/faq/view.jsp?EID=915898
It kind of outlines how you might have a list page with editable data.  I
think it's kind of hokey, however I haven't tried it yet.  It might work
just fine.

I hope that helps.

Order Detail page with editable line items

[Greg Blomqusit]

I have a problem that I'm sure is quite common.  However, I have not seen
any decent examples
of how this might be implemented using Struts, so any suggestions would be
greatly appreciated.

The problem is this:  I have an order detail page that has a list of line
items with editable data
inside each line item.  The user is allowed to select which product they're
ordering and what quantity
of that product per line item.

I can figure out how to create an ActionForm bean that is able to convey the
values to the JSP
using a collection of line item beans inside the ActionForm.  And, I can
figure out how to code
the JSP to output the values into the form elements using the
 tag.

However, what I'm having trouble with is submitting the values back to the
Action.  How can
Struts repopulate the collection inside the ActionForm?  Or, if I should not
be using a collection
to represent the line items, how else should I do it?  In the case of not
using a collection to
represent the line items, how do I get Struts taglib to populate the form
elements in the JSP?

I've attached a gif file that depicts the prototype of the screen I'm
talking about, for those of you
who are visual thinkers.

Any help is appreciated!

Thanks!

[Greg Blomqusit]

Can you elaborate?  Or, point me to a decent example?
Thanks Brandon (and Hunter).
