The form could have many thousands of rows and my real problem was determining which cell had been edited. I'm not sure if it's correct, but I solved this by doing the following:
1. Each editable textfield in the HTML form has a dynamically constructed name. This field also has an "onChange" handler that dynamically adds a new new hidden element (dirtyCell) to the page to track the changed fields.
2. The textfields and hidden elements are passed to the action.
3. I iterate over the array of "dirtyCell", get the textfield name that has been edited, and retrieve the contents from request parameter map and then persist it.
If anyone knows of a better way to do it, I'd love to hear it.
Thanks,
Dennis

Hello,
U can try this.Most probably this will work.
U can store the data in the Arraylist map this list to form level Arraylist.
use logic:iterate tag to display data from the form Level ArrayList with id and property as the form level list.
tell me whether @ runtime r u going to add any rows??
Correct me if i am wrong.

G Ravi.

Subject: How to handle a table with an unknown number of rows
So, I can't get my head around this. Is it possible for an ActionForm to
model an HTML table with an unknown number of rows?
The context is that I have a page that displays the raw results of a query.
One of the fields is always editable by the user, so I need to be able to
submit a form to persist the edited data. However, I don't know the size of
the resultset in advance, so I'm...stuck.
BTW, I'm currently constrained to using Struts 1.0.
Thanks,
Dennis
