[jboss-user] [JBoss Seam] - Problems with navigations with null outcomes

[fernando_jmt]

Hi.

I am just changing all navigation rules from faces-config.xml to pages.xml.

Then when my action returns a null outcome it does not redisplay the current page.

I have this method in my component:


  | @Stateful
  | @Name("userManager")
  | public class UserManagerAction {
  | ...
  | public String create() {
  |             em.persist(user);
  |             em.flush();
  |             return "userList";
  |         } catch (EntityExistsException e) {
  |             return Outcome.REDISPLAY;
  |         }
  | }
  | }
  | 

And according the documentation (1.1.6) I tried two configuration in my pages.xml:

a) (This is not in the docs, but I saw it in this forum)


  | 
  | <page view-id="/user/new.xhtml" no-conversation-view-id="/user/list.xhtml">
  |         <navigation from-action="#{userManager.create}">
  |                 <redirect view-id="/user/list.xhtml"/>
  |         </navigation>
  |     </page>
  | 
  | 


b) (according the book)


  | <page view-id="/user/new.xhtml" no-conversation-view-id="/user/list.xhtml">
  |         <navigation from-action="#{userManager.create}">
  |             <rule>
  |                 <redirect view-id="/user/list.xhtml"/>
  |             </rule>
  |         </navigation>
  |     </page>
  | 


In the both cases (a, b) after userManager.create() returns null or Outcome.REDISPLAY the current page is not redisplayed, I always get the list.xhtml page.


Anyone knows why?

Could this be a bug? or is it my fault?

Please help me.

BTW, it could be good idea to add to Outcome class something like:
Outcome.SUCCESS. This because in these cases (using navigations with String returning methods and pages.xml navigations) the outcome sometimes does not matter. I know we can use void methods, but adding error messages and checking those in the navigation rule involves more configuration steps, I think unnecessary for these cases. What do you think?



Thanks in advance.
