Re: Dynamic number of properties in an ActionForm?

[FrenzyGNX]

You can use a Collection or array to hold the data and
use  or  tags to interate
through the collection and display the items.

You can use a Map backed form to send back the values.

RE: Dynamic number of properties in an ActionForm?

[Andrew Hill]

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.

Subject: 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
