Validation of multiple textfield in a dynamic ListView
Hi
I have a validation problem that I can figure out how to do:
I have build a dynamic table for the user to enter data into text fields.
I am using the ListView component and some ajax behavior.
Users can add and delete rows of the table. Everything works well, except
for the validation.
One of the column in the table is a port number. And guess what, port values
must be unique in the table.
How can I do that kind of validation?
I was thinking of using a Form Validator, but the problem is that form
components are added and deleted dynamically.
Any idea?
Thierry

however you want. you have the object graph. you can either use a
visitor to locate whatever components you want, or you can keep direct
references, or you can use a visitor to broadcast an event. completely
up to you.

Ok, that is a good start.
Now how do I access the form data within that method?
Is there any documentation on that or any example?
Thanks!
