Facing a problem in rendering updated data

Question

Hi All,
Am pretty new to JSF and I have a problem. Any help is much appreciated. Thanks.
I have a page called LicenseSearch.jsp which is tied to a LicenseSearch.java backing bean. The LicenseSearch.jsp has lot of input components which are populated by appropriate methods in the bean by fetching data from the database.
When the page is loaded initially things work fine and data is displayed properly. When I navigate to another page and change some data and come back to LicenseSearch.jsp, the updated data is not visible in the UI components.
Please help.

Here is the code
<h:outputLabel for="companies" value="Companies" styleClass="formFieldLabel"/>
<h:selectManyListbox id="companies" value="#{backing_LicenseSearch.selectedCompanies}" size="5">
    <f:selectItems value="#{backing_LicenseSearch.companies}"/>
</h:selectManyListbox>
<h:message for="companies" styleClass="error"/>
public List getCompanies() throws IOException
         try
              logger.info("getCompanies called");
          this.companyMenuItems = createMenuItems(EntityFactory.getInstance().getAll("Company"));
         catch (Exception e)
              logger.error("Exception in License Search", e);
            ErrorPage.getInstance().addError(new ErrorMessage("License Search Failed: " + e.getMessage(), e));
            FacesContext.getCurrentInstance().getExternalContext().redirect("Error.jsp");
          return this.companyMenuItems;
<managed-bean>
          <managed-bean-name>backing_LicenseSearch</managed-bean-name>
