Session OR Request Scope - JSF

[bansi <ma...@yahoo.com>]

My Search Backing Bean (JSF)  displays the resultSet as list of object
properties along with a hyperlink for Edit/Update.

When i click on the hyperlink Edit , i am passing "id" value of the object,
so that i can load the object , which eventually renders data on Update Form



I have defined the "id" as managed-property in faces-config.xml . It works
only if the managed-bean is defined under "request" scope. Otherwise it
throws the following exception for Session scope



javax.faces.FacesException: Property id references object in a scope with
shorter lifetime than the target scope session



Please note my requirement is to have managed-bean in session scope as it
has lots of other stuff like h:selectManyListBox which works only in session
scope



Any pointers/suggestions will be highly appreciated

Hi Cagatay
Thanks for quick response. I tried  <t:saveState id="save1" 
value="#{searchBean.id}" /> but it didnt help
Having session scoped bean is really a requirement for me as i am doing lot
of other stuff like using h:selectManyListBox to add/remove Roles etc

I have id defined as the property in my backing bean i.e. session-scoped
managed bean with a managed property bound to a querystring parameter id

<managed-bean>

      <managed-bean-name>userBean</managed-bean-name>

      <managed-bean-class>project.UserBean</managed-bean-class>

      <managed-bean-scope>session</managed-bean-scope>

      <managed-property>

            <property-name>userId</property-name>

            <value>#{param.userId}</value>

      </managed-property>

</managed-bean>

My workaround is to get the request parameter from the ExternalContext in my
property's getter method
Any pointers/suggestions on how to do this will be highly appreciated

Hi,

That's because in jsf ioc you cannot inject objects with short scope to the
ones in longer scope, like in this request-session example.

Is the session scoped bean really a requirement, maybe you can try
t:savestate instead of http session to keep the data alive.
