As we all know, when we render a component of the JSF web application, we will lose property value. We have two solutions:

  1. Set the ManagedBean type Session in face-config.xml

  2. Set property Of Managed Bean static type. E.x:

    Public static String txtName Ex.

I want to find a way not used the second way (so many they will only web browser access to a single static variable) and not to use a SessionBean like the 1st way.

Is there any solution to solve this problem?

Just use the view scope. It's designed for exactly this purpose. Remembering the values responsible for the view state across ajax requests on the same view.

@ManagedBean
@ViewScoped
public class Bean {

    // ...

}

  • thank you so much for your suggestion. Can I define ViewScoped in face-config.xml like this: userBean com.demo.bean.UserBean view – Hung Phan Dang Aug 14 '12 at 21:00
  • Yes. How exactly does that fail for you? Or haven't you even tried it at all? In the future, please try before asking :) – BalusC Aug 14 '12 at 21:02
  • I tried over 20 times and it's still failed. The property value has been save but so unfortunately, the popup didn't show. I will show my demo error few minutes later – Hung Phan Dang Aug 14 '12 at 21:52
  • Apparently you're (implicitly) recreating the view everytime. Some code in flavor of an SSCCE would definitely help to spot the cause of the problem :) – BalusC Aug 14 '12 at 22:26
  • http://www.youtube.com/watch?v=FTvd1NrAjxU&feature=youtu.be Here is my web bug when I want to render a popup using viewScope in managed Bean – Hung Phan Dang Aug 15 '12 at 07:16
  • It's a nice video, but you're merely demonstrating/confirming the bug which you've already described in the question. The video did not show the full code in its entirety, let along in an SSCCE flavor, but I saw in an occassion in the video that you were using the `binding` attribute. That won't work in combination with the view scope due to JSF issue 1492. Get rid of the `binding` attributes or look for alternate ways. – BalusC Aug 15 '12 at 10:19
  • Oh thank you, I will try to make better videos in next time. I've change way to show popup, not use binding. But unfortunately it still bug :(, the bug is the same with the bug when i use binding. I will send you my project example soon :). I'm very glad to talk with you :) – Hung Phan Dang Aug 16 '12 at 14:53
