1. Re: How to retrieve current view ?
gavin.king Jul 3, 2006 12:44 PM (in response to jboss-nth-fan)You mean you want to discover the current JSF viewId?

jboss-nth-fan Jul 3, 2006 12:54 PM (in response to jboss-nth-fan)Thanks for your almost quick response Gavin, great support !
I'm thinking if the JSF viewId would be the correct way to access it or does Seam store that reference or handler somewhere else?
If so how should I access it: standard JSF or via a Seam method ?
Yeyo. -

gavin.king Jul 3, 2006 12:56 PM (in response to jboss-nth-fan)Just the standard JSF way: facesContext.getViewRoot().getViewId()

jboss-nth-fan Jul 3, 2006 1:14 PM (in response to jboss-nth-fan)Thanks Gavin.
Maybe a bit off topic , but in the DVD sample in the login.xhtml page I've modified in my own prototype to use s:link instead of the<h:commandLink action="#{editCustomer.startEdit}">Create Account</h:commandLink>
but did not work. I had the idea that both commandLink and s:Link would be somewhat interchangable but it seems not.
Can you point to resources providing insight on the differences?
Thanks -

gavin.king Jul 3, 2006 8:51 PM (in response to jboss-nth-fan)No, they are not interchangeable. s:link does _not_ submit the form!

6. Re: How to retrieve current view ?
norman.richards Jul 4, 2006 12:24 AM (in response to jboss-nth-fan)That's actually not the issue here though. The difference here is that the h:commandLink action executes during the normal invoke application phase. With an s:link action, the action executes during as a page event during the render response phase.
If a pageflow starts during the invoke application, it should start with a start-node. When started from ender response, it needs to begin with a start-page. This is somewhat awkward because you have to make sure that you are on the correct starting view. (s:link should contain both a view and an action attribute)
Hope that helps. -
7. Re: How to retrieve current view ?
gavin.king Jul 4, 2006 1:14 AM (in response to jboss-nth-fan)I can treat pageflows that start from a page action the same as pageflows that start during INVOKE_APPLICATION if you think that would be more natural/correct, Norman. But the idea is that page actions do not _usually_ change the view id, so you are already at the start-page when the action is called...

norman.richards Jul 4, 2006 2:01 AM (in response to jboss-nth-fan)I was just pointing out the difference with regards to the way things are implemented now and why the two styles of invocation didn't act the same with regard to pageflow. I didn't understand the distinction myself until we talked about it a month or two ago, and so I definitely think most users would be confused by this.
I *think* I would prefer the the page action and invoke application action to work the same for pageflows, but even if they are different, I would expect an s:link action to work like an h:commandLink action.
Maybe some other Seam users here can comment on what they feel is more natural.
