Dynamic managed bean names

Question

Hi!!
in my application i make code that must be present in every JSP pages. For that, i put it into a separated JSP page who is included in the other JSP (using <jsp:include> tag).
My problem is that each JSP who include the repetitive JSP, uses a different managed bean name.
For example, the page who is included is:
<f:subview id="navigation">
      <h:inputText value="#{name-of-bean.navigation}" styleClass="inputNav" readonly="true" />
</f:subview>When this code is included into the pages, each page must use a different "name-of-bean".
I try with:
<jsp:include page="navigation.jsp">
     <jsp:param name="beanName" value="AlfaBean" />
</jsp:include>and in the child JSP:
<h:inputText value="#{requestScope[param.beanName].navigation}"
styleClass="inputNav" readonly="true" />but dont work.
I try with:
<h:inputText value="#{resources[param.beanName].navigation}"
styleClass="inputNav" readonly="true" />but dont work.
Some body can help me??
PD: Sorry my bad english!!

JSF creates a managed bean at the time when firstly it evaluates the
corresponding value binding expression, such as "#{AlfaBean.someProp}".
Your JSP files include no expression including the name of the bean.
Although it may be a very tricky code, here is a sample used for you problem:<h:outputText value="" rendered="#{AlfaBean.someProp != null}"/>
<jsp:include page="navigation.jsp">
     <jsp:param name="beanName" value="AlfaBean" />
</jsp:include>
