[jboss-user] [JBoss Seam] - Re: view vs action attribute (Explanation needed)
Action can be a call to a method in a session bean. If that method returns a string, that string is used as the view identifier. If that method has no return (void) or it returns null, then the view specified by view= is used as the view. If the action returns null AND there is no view=, then the same page is just redisplayed. So, it is a bit confusing, but here's how I use it: Most of my session beans are SFSBs, conversation scoped. They have a @Begin(join=true) method. I make this @Begin method return void, and when I want to navigate to one of them, I use that @Begin method as the action and then specify view=/foo. That way I make sure there is an active conversation when the /foo page is first rendered, so I don't get LazyInitializationErrors. I'm not enough of a Seam pro to know if this is the absolutely right way to do this but it certainly does work.

view takes a view-id to navigate to. action takes an action method (el) or a string which specifies a logical (navigation) outcome (either JSF faces-config.xml or pages.xml).

Thanks to all of you. What is your opinion with my example code? Should it even render /editUser.xhtml? With your explanation, i think NO But it does.

Of course it should render editUser.xhtml in your example. That is the action you have specified. In most cases the action is a snip of EL that gets called, and the string that results from that call is used as the next view. In your case, you have used a static string instead of EL. It's doing what we expect it would do.
