Re: How to create form rows dynamically
Probably you should try using the validator framework for validation. you could avoid using the custom form in case you just use it for validation. You could add in your validations into the validation-rules and use it. Make sure your form has sesion scope. That apart, Im not sure why you don't get the updated values...

Re: How to create form rows dynamically
Hi,
I followed the example you attached and it seemed to have worked except when
I submit the form I cannot get at the form values.
For example when I submit the form if the newAmnt text box gets a new value
of say 10.00, the value on the server side is still returned as 0.00 (the
original value).
Would you know what might cause this? I am using a form which extends
DynaActionForm so I can use the validation method.

Title: Re: Problem using indexed properties and validator framework
In the struts-config.xml:
form-bean name=ManageAccountsForm type=application.EditUsersForm
form-property name=users type=application.UserBean[]
/form-bean
action-mappings
action
path=/application/EditUsers
type=application.EditUsersAction
name=EditUsersForm
scope=session
forward
name=success
path=editUsers.jsp
redirect=false
/
action-mappings
In EditUsersAction.java execute method
// get collection of users from the database
Collection users = getUserBeans ();
// put collection into form as an array for editing
form.set ( users, users.toArray ( new UserBean[0] ) );
In editUsers.jsp
logic:iterate id=users name=EditUsersForm property=users
html:text name=users property=name indexed=true
/logic:iterate
In the produced HTML:
input type=text name=users[0].name /
If you need to client side validation, you'll probably need to write your
own JSP to deal with the element above.
As for using validate.xml to validate on the server side. I've never tried
it with arrays, I just iterate over them in the validate (...) method of the
form, like so:
UserBean users[] = (UserBean[]) form.get ( users );
for ( int i = 0; i users.length; i++ ) {
// check on the attributes of UserBean users[i]
}
Hope that example clears it up for you.

For an Array in a DynaForm property, you can either set the size in the
form-property descriptor or, in the case of a session form, pre-populate
the
Array in your action with the number of elements you desire.

I am also unsure as to how to access these values when I get to the form/action classes. Any help would be much appreciated! There are a few ways to do that. The most obvious (according to me) would be to have a Billing (for instance) class, with all the attributes that suit you, then : - use a lazy list (go to http://wiki.apache.org/struts/StrutsCatalogLazyList for more information about them) to store them. The use of LazyList instead of classical List (with ArrayList) is all about indexes : when you start from the server and you display the items stored in your list, all is fine. (something like : !-- titles/headers go here -- logic:iterate id=item name=myList html:text name=formList property=payment indexed=true/ html:text name=formList property=oldAmnt indexed=true/ html:text name=formList property=newAmnt indexed=true/ html:text name=formList property=dateindexed=true/ br/ /logic:iterate ) But when the user clicks on the submit button, a horrible thing happens : IndexOutOfBoundException (because a new List is instanciated from the server side - the old one has been lost as it is a new request - and currently, something like formList.get(0) returns null, which isn't what Struts expected). So you have to make some mechanism to return an object (preferably of the right kind) so Struts remains happy. Hence the LazyLists. -- Stéphane Zuckerman - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

It does not display the list by itself, but sample code contains the helper action which displays the list and all needed buttons for CRUD operations: http://struts.sourceforge.net/strutsdialogs/crudaction.html The item list is displayed using array list of items.
