Beans in session scope lifecycle

[Charbel Abdul-Massih <ca...@soundbite.com>]

Hello,

I have a wizard flow that utilizes a backing bean in session scope...if
a user should cancel out of the wizard at any point, is there a way to
reset the backing bean and its properties??? Or better yet, is there a
way to completely remove the bean from the session so that next time the
user enters the wizard, it's instantiated again???

 

Thx,
Charbel

Hi,

sounds that you need t:saveState in this case.

It pushes the bean in a special kind of scope, which durates it longer
than request and shorter than session. Means it is an ideal choice for
all kind of page-scope stuff, such as a wizard.

Usage:

<t:saveState value="#{wizardBean}"/>

cheers,

Gerald

Try this:

 

FacesContext.getCurrentInstance().getApplication().createValueBinding("#
{ManagedBeanName} ").setValue(FacesContext.getCurrentInstance(), null);

Hi,

    When user cancels out of wizard then you can
execute the following lines of code :

FacesContext facesContext =
FacesContext.getCurrentInstance();
		HttpSession session = (HttpSession)
facesContext.getExternalContext().getSession(false);
		if (session != null) {
			session.invalidate();
		}

This will remove the session objects and whenever user
reenters the system, session beans will be
reinstanciated.

regards..
Arvind
