Can somebody explain me this?

Question

Hi,
In my recent project using the JavaServer Faces i discovered a problem with my project that i don't quite seem to understand.
My bean function is called twice and i thought it would only be called once. Let me explain my problem. I created a small and simple example so anybody can explain me why this is happening.
I have 2 .jsf files:
- The first one (myJSFSelection.jsp) allows the user to select from a menu which information he will want to see. (Which this information is represented in a bean - MyFirstBeanSelection.java)
- The second one (myJSF.jsp) sees which of the options the user has selected and presents in the UI the information regarding the selection (Represented by another bean - MyFirstBean.java)
My FirstBeanSelection holds the value selected by the user and MyFirstBean has a function (getInfo()) that will check which is the value from the MyFirstBeanSelection and it will return the value associated to the selection.
In my faces-config.xml i have defined the following:
<managed-bean>
          <managed-bean-name>myFirstBeanSelection</managed-bean-name>
          <managed-bean-class>
               bpr.userPortal.beans.MyFirstBeanSelection
          </managed-bean-class>
          <managed-bean-scope>session</managed-bean-scope>
</managed-bean>
<managed-bean>     <managed-bean-name>myFirstBean</managed-bean-name>
          <managed-bean-class>
               bpr.userPortal.beans.MyFirstBean
          </managed-bean-class>
          <managed-bean-scope>session</managed-bean-scope>
          <managed-property>
               <property-name>bean</property-name>
            <property-class>bpr.userPortal.beans.MyFirstBeanSelection</property-class>
            <value>#{myFirstBeanSelection}</value>
          </managed-property>
     </managed-bean>I am sure that the function getInfo() is being called. It is called two times. I am sure i have done something wrong here. Can anybody help? Thanks in advance.

Hello!
If you think your method is called more then one time, i would implement a Logging-System (i.e. log4j) or a console-output in your method.
Then you can check, if your method ist called correct.
