I use both actionListener (to set focus on selected tab, and set navigation 
case outcome corresponding to this tab by detecting its id value) and action 
(to return outcome string stored in the bean by actionListener) and navigation 
is okay now. I get moved to correct pages by clicking on its tabs, HOWEVER now 
the tabs are not being selected correctly. I move to a right page but the wrong 
tab is being selected. And it seems to be delayed by one click. Namely the 
focus of selected tabs get on the one that I previously clicked on. Now I found 
out after some testing that this happens because I am loading different jsp 
files every time I click on the tab. If I reload the same jsp page (I set all 
tabs to point to the one same jsp page) tabs are being selected correctly. This 
makes me think there is an issue with page scope and tab component. Seems to me 
that every time I load different jsp page (they are all including common code 
section for tabs), a new instance of tab component object is being created and 
it has no way of tracking its state from the previous page. Shouldn't these tab 
component objects be STATIC so that they retain their values across multiple 
pages. I mean shoudn't all different pages be refferencing one same object 
instance created when the first page containing tab components was loaded. And 
shouldn't all subsequent (different) jsp pages be still refferencing that same 
object?

Am I missing something here? Is there a way to make every tab component object 
STATIC across different jsp pages?

Subject: Re: ActionListener for navigation tabs
 
Hi,

Instead of using "actionListener", you may can use "action" like this:

<tr:commandNavigationItem text="More Info" action="guide.moreInfo"/>

or

<tr:commandNavigationItem text="More Info" action="#{
demoCommandNavigationItem.moreInfo}"/>

where #{demoCommandNavigationItem.moreInfo} is:

  public String moreInfo()
  {
    return "guide.moreInfo";
  }

Now, if you want to use actionListener for example to set more properties on
the bean, you can implement both an actionListener and an action.  If you
wanted a single bean for all of your 4 tabs, the actionListener can have
code to detect which tab was clicked, save off that info, then in the
action, you can return a particular action string for the particular tab
that was clicked.

Regards,
Matt
