Hi:
I had a concern about how to manage parameters that are flying between the server and the client.
It will worth if we have an attribute in the form that define when we are
waiting or not for a parameter back from the user?
do you mean something like read-only fields?
I know woody has some formulas, I was not full review woody. :)
I was thinking in some type of "formulas" or "equations" that we can send
to woody and let woody calculate them.
sending formulas to woody? Me understand not :-)
ie: a tipical invoice (master-detail):
Date: 29-jul-2003 N° 2300 Client: Cocoon
------------------------------------------- Quantity Item Unit Price Amount ------------------------------------------- 2 pen $1.00 2.00 1 pencil $0.50 0.50 ------------------------------------------- Subtotal: 2.50 Shipping: 1.00 Total: 3.50
Here we have some fields that are sended from the model (amount, subtotal,
total), but we dont need it back from the form.
And here I get the impression that you're asking for one-directional binding? If so, checkout the readonly attribute on the wb:field element.
Not sure I understood what you were asking for, but feel free to explain further.
I guess Antonio is talking about computed fields. For example, the "subtotal" above is the sum of all "amount" fields. Amounts are read-only, and subtotal is a fake field that has no binding to the application data model.
I'm wondering if "read-only" is a property of the binding or of the field itself. It should be on the field, since it changes both the field rendering and it's handling of requests (it should not be parsed).
