OptionalValidator - Required validator - compound components

[Andrew Robinson <an...@gmail.com>]

After looking more at the source code for the optional validator
framework, it doesn't look to me like it will support data tables,
trees and other complex comonents that render children multiple times.

It walks the component tree looking for required components, but it
will never check rows of a data table for example as it won't iterate
the rows, only the components once. Don't suppose there is a way
around this. I have no idea why JSF has the required attribute instead
of a required validator.

Is this true, or did I miss something?

Yes, tree traversal is not possible.

This is my most wanted feature for JSF 2.0! We could implement something
like this along the lines of invokeOnComponent.

Martin

Hi,

Yes, tree traversing won't work in case of a datatable. I always think
required attribute is a mistake, it should be a validator instead.
