Wiring managed beans - managed-property not updated.

Question

I have a search page with a text field for entering a substring search.
Upon clicking submit, a list will be displayed below based on the given substring.
I wired two managed beans together: one was a substring of type String,
the other a facade that has a getSubstring and setSubstring method.
The Facade also has a getList method that returns a list.
Session:<h:outputText value="#{substring}"/>
List: <h:outputText value="#{Facade.list}"/>
What happens is that the session variable is being updated everytime I submit the form
but the list is the one that was displayed the very first time the form was submitted.
Subsequent changes to the substring has no effect on the list.
I tried this because I read somewhere that this is an alternative to putting the
properties of the form together with the facade.
However, upon reading the documentation of the struts-config,xml,
The managed-property will only be set at the creation of the managed bean.
and not everytime the tag referencing the bean is evaluated.
Any workaround to making this work?
Given the scenario above, what is the best design for it?
I'm thinking of putting an action field in the commandButton
and then set the list as a session variable,
which will be accessed by the jsp after the action forwards to the page.
Is this strategy any good?

Sure... here it is...
<faces-config>
<managed-bean>
<managed-bean-name>substring</managed-bean-name>
<managed-bean-class>java.lang.String</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
<managed-bean>
<managed-bean-name>Facade</managed-bean-name>
<managed-bean-class>com.Facade</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<managed-property>
     <property-name>substring</property-name>
     <value>#{substring}</value>
</managed-property>
</managed-bean>
</faces-config>
public class GroupingFacade {
     private String substring;
     public void setSubstring(String substring;
          this.substring=substring;
     public String getSubstring(){
          return substring;
     public List getList(){
          ArrayList list=new ArrayList();
          //Get list from DAO
          //DAO.getList(substring);
          return list;
}
