Dynamic number of properties in an ActionForm?
I have a little question. How do I setup a page with a form where I
don't know the number of properties in the form at design time? I have a
table of rows with a known number of columns but I don't know the number
of rows at design time, so how do I implement this using an ActionForm?
I need to read back the values also, not only display them...
Regards,
BTJ

You can use a Collection or array to hold the data and
use <logic:iterate> or <c:forEach> tags to interate
through the collection and display the items.
You can use a Map backed form to send back the values.

The 'simple' way involves using properties that take an array
If your columns are foo, bar, etc... you could have:
setFoo(String[] foo)
setBar(String[] bar)
but... a *better* way would probably be to leverage the power of nested
action forms - where you have a property on your form whose value is a
collection of (nested) forms - each of which has the data for one row of the
table.
