Re: Imbedding a Form Inside a Sruts logic:iterate tag

["David Morris" <David.Morris@xxxxxxxxxxxxx>]

Stephen,

You really don't need to embed form elements in your loop. I haven't
used 1.0.2 in quite a while so I can't give you a 1.0.2 example. What
you can do is create an array or some form of Collection on your form
(or other bean if you have overidden it) along with a setter that takes
an index.

For example, you might have a class called OrderDetail that has
lineNumber, quantity, and amount properties. Both of these would have
get/set like getQuantity(). On your form you might have an ArrayList
named orderDetails with a getter/setter.

In your JSP, you would refer to the properties as
property="orderDetails.lineNumber", etc. You would embed these
references in html:hidden, html:text tags, etc. I use the nested tags
for this, which are somewhat different than the logic:iterate tags, but
from what I remember, your iterate tag sets the name for the detail line
tags.

Hello All,
 
I am using Struts 1.0.2 to display a table using a logic:iterate over an
array list in the placed session scope.  This works great until I try to
imbed a html:form into the logic:iterate to make each row updateable (I
need
to allow the user to change a value in the table). I am then attempting
to
use an update button on each row to trigger reloading the arraylist with
the
user supplied value.  The jsp errors out each time I add a form tag
inside
the <TD></TD> that is defined within the logic:iterate tag.   If I
create a
table with a fixed number of rows (without a logic:iterate) it works
fine.
I will not be able to do this as a solution as I am loading the results
of
an SQL query to the table and I will not know how many rows I will need.
Has anyone created a table using the logic:iterate tag with updateable
fields?  I would appreciate some pointers here on how to proceed .
 
Thanks
