Description

When using the ViewConfig in CODI we not only get type safe navigation but also know the 'connection' between views and their backing beans. We already support annotations like @PreRenderView and likes for such beans.

We should also support the direct annotation of view parameters directly in the backing beans.

instead of declaring the view parameters in the xhtml:

<f:metadata>
<f:viewParam id="versionParam" name="version" value="#

{backingbean.versionString}

" required="false"/>
<f:viewParam id="searchString" name="s" value="#

{backingbean.searchString}

" required="false"/>
</f:metadata>

we can maybe use an annotation directly in the backing bean:

@Named
@RequestScoped
public class Backingbean {
@ViewParam(required=false, name="version")
private String versionString;

@ViewParam(required=false, name="s")
private String searchString;

@PreRenderView
private void dosomeinit()

{ ... }

}
