[seam-issues] [JBoss JIRA] Commented: (SEAMFACES-122) Find a way to use the @ViewConfig enums to provide type-safe navigation rules

Lincoln Baxter III commented on SEAMFACES-122:
----------------------------------------------
This would probably be simplest using a two-part strategy for navigation. The combination
of a Utility class and a JSF NavigationHandler.
For instance:
{code}@Inject
private Navigator nav;{code}
{code}public String myAction()
{
/*
* Redirect to (HTTP GET) the specified view. (faces-redirect=true)
*/
return nav.redirectTo(viewEnum);
/*
* Navigate (JSF) to the specified view.
*/
return nav.navigateTo(viewEnum);
/*
* Return a NavigationBuilder, then navigate (JSF) to the specified view.
*/
return nav.toView(viewEnum).navigate();
/*
* Return a NavigationBuilder, add a ?query=parameter, then redirect (HTTP GET) to the
specified view.
*/
return nav.toView(viewEnum).addParameter("p", value).redirect();
/*
* Return a NavigationBuilder, add a ?query=parameter, then navigate (JSF) to the
specified view.
*/
return nav.toView(viewEnum).addParameter("p", value).navigate();
}{code}
This relies on the Navigator to serialize any navigation information into String form so
that it may be consumed by a custom NavigationHandlerImpl provided by Seam Faces and
registered in faces-config.xml.

Key: SEAMFACES-122
URL: https://issues.jboss.org/browse/SEAMFACES-122
Project: Seam Faces
Issue Type: Feature Request
Components: View Configuration
Reporter: Brian Leathem
Fix For: 3.1.0.Tracking
Option 1) instead of using a @ViewPattern annotation, instead pass it to the constructor
of the enum, to be stored as a property of the enum.
Problem: the application developer would have to implement the constructor
Option 2) require the developer to implement an interfaces, that specifies a setViewId
method for an enum value, programmatically set that viewId with what is in the
@ViewPattern annotation
Feel free to provide more implementation options in the comments!
