Seam: Where you from!?

[Ryan Waggoner]

Hey guys,
I am having trouble trying to find out how to do something like:

   
if(from page 1)
 return "homePage"
else if(from page 2)
  return "otherPage" 

Anyone know how to make my pseudo code come to life with Seam?

Thanks!

public String redirectTo(String strPage){
  if(strPage.equals("page 1"))  
  return "homePage"  
 else if(strPage.equals("page 2"))  
   return "otherPage"  
}
  

The return type is a string from an action.

In pages.xml , you can define the navigation as,

  

<page view-id="XYZ.xhtml">    
        <navigation from-action="#{redirectController.redirectTo}">
            <rule if-outcome="page 1">
                <redirect view-id="/homepage.xhtml"/>
            </rule>             
        
            <rule if-outcome="page 2">
                <redirect view-id="/otherPage.xhtml"/>
            </rule>  
       </navigation>     
</page>

  

Let me know if this helps!!

That looks like what I want Vivek...


But how do you get the strPage?

Or rather when I call the redirect method, where am I calling it from, and what do I pass in?

[Vivek Murugesan]

What's your scenario? I thought you have an action method and based on it's logic you have to navigate to the corresponding page.

I have a userList page, which lists all of my users. You can click a user, then edit & save them.
I have an add/edit user page, which does just that. When you save the add/edit, you are forwarded to a confirmation page.

I am trying to figure out how:

When someone clicks the save
If they came from the userList page, send them back.
If they came from anywhere else, send them to the confirmation page.

The save button is linked to a method in my stateful bean, userEntryBean.

Maybe I can ask, how, in my code, can I see where the person navigated from.

Any ideas?

Thanks!

A simple approach would be to set a boolean value in a bean and based on the value you can redirect, it can be set to 'true' when navigating from userList page.

or

You can refer the API,org.jboss.seam.faces.Redirect -> Redirect.instance().captureCurrentView();

and you'll have to make corresponding navigational entries in pages.xml.

I think I will be going the boolean route.

Thanks a lot for the help!
