Netui:checkbox usage

Question

I'm looking for an example of using the netui:checkbox (or group, etc), in a jsp
page within a page flow. In particular, I want to render multiple rows (using
the netui:repeater), with a checkbox on each row. When the user submits the page,
I want a collection of all the checkbox's checked!
Is this possible?
Thanks.

Greg--
Here's a basic sample that shows using the <netui:checkBox/> tag
inside of the repeater.
The repeater renders Widget[] on the page with a check box per Widget
which changes the "boolean" property on a particular Widget.
What you'll get on POST are updates to all of the "available"
properties on the Widget[] inside of the page flow's "widgetForm"
proeprty. If you need a Collection from that, you can always convert it
by hand. You could also use a Widget List instead of a Widget array
inside of the WidgetForm.
One thing to notice here is that the repeater binds to a property of
the page flow instead of binding to an action form. This means that
values are POSTed directly into the page flow and that you'll need to
perform validation by hand. The sample is this way simply for
simplicity; if you'd rather POST into a FormData object so validation is
called by the framework as usual, you can use Struts merge to scope a
form bean into the session for the "postback" action.
Hope this helps...
