SV: [jira] Commented: (SHALE-425) ViewControllerMapper allows mapping only to one bean

[Hermod Opstvedt <he...@opstvedt.com>]

Hi

I think maybe there is a misunderstanding of idea behind the ViewController.
It is exactly for mapping one Controller! against a view - Hence the name
ViewController.

Just out of curiosity: Why would you want multiple viewcontrollers against a
view?

I think you may have misunderstood something. You can use multiple beans! To
feed a view with data.

Matthias Wuttke commented on SHALE-425:
---------------------------------------

Another (IMHO good) mapping strategy would be to allow backing beans to
programmatically register themselves with the view mapper:

MyCoolDynamicViewMapper.registerBean(ctx.getViewRoot().getViewId(),
"myBeanName");

This allows the use of abstract super classes for backing beans and allows
for backing beans that are responsible for different views.

> ViewControllerMapper.mapViewId(String viewId) allows only to map a view to
a single bean. A key feature of JSF (IMHO) is the ability to have multiple
backing beans / view controllers that contribute to a single page. An
extension of this interface could allow other mapping strategies to
associate multiple beans with a given page that can then receive phase
change events. A possiblte mapping strategy would be a
XmlViewControllerMapper which takes a XML file that associates view ids with
bean names.
