Issue with passing parameters from JSP to Backing bean

Question

hi ,
I have an issue in passing parameters from my JSP to backing bean. I want to fetch the parameter from my URL in backing bean .This is how i am coding it right now. But the parameter companyID returns me null.
URL http://localhost:8080/admin/compadmin.jsp?companyID=B1234.
In my backing bean
FacesContext context = FacesContext.getCurrentInstance();
String companyID = (String)context.getExternalContext().getRequestParameterMap().get("CompanyID");
     public void setCompanyID(String companyID)
          this.companyID=companyID;
     public String getCompanyID()
          return this.companyID;
faces-config.xml :
   <managed-bean-name>admincontroller</managed-bean-name>
          <managed-bean-class>com.admin.controller.AdminController</managed-bean-class>
          <managed-bean-scope>request</managed-bean-scope>
          <managed-property>
               <property-name>companyadminbean</property-name>
               <property-class>com.admin.model.AdminBean</property-class>
               <value>#{companyadminbean}</value>
                     </managed-property>
                    <managed-property>
                             <property-name>companyID</property-name>
                          <value>#{param.companyID}</value>
                         </managed-property>Please let me know if iam missing something.Appreciate your help in advance

Thanks very much for your input. I made changes to my bean accordingly. Actually the method getAdminType() is a not a getter of a property. It's just a method which iam calling in AdminController bean constructor to verify whether the person is System Admin or Client admin. So now the issue is inspite of making changes still the link "Copy Users" shows up for Client admin too which is incorrect.
My Administrator bean:
public class Administrator {
  boolean GSA=false;
  boolean SA=false;
  public Administrator(){}
public boolean isGSA()
    return GSA;
  public boolean isSA()
    return SA;
  public void setGSA(boolean value)
    this.GSA=value;
  public void setSA(boolean value)
    this.SA=value;
}My backing bean:
public class AdminController {
private AdminBean adminbean = new AdminBean();
public AdminController(){
int userID=1234;
this.getAdminType(userID);           
public void getAdminType(int userID)
         Administrator admin = new Administrator();
         if (userID<0) return;
         try{
             if(Rc.isGlobalSystemAdmin(userID)){
                  admin.setGSA(true);
                          }else if(Rc.isClientSystemAdmin(userID)){
                  admin.setSA(true); // i could see these values setup correctly in the admin bean when i print them
             adminbean.setAdmin(admin);
              } catch (Exception e){ }
Admin Bean:
public class AdminBean {
private Administrator admin; 
public Administrator getAdmin()
                    return this.admin;
          public void setAdmin(Administrator admin)
                    this.admin = admin;
faces-config.xml
<managed-bean>
          <managed-bean-name>admincontroller</managed-bean-name>
          <managed-bean-class>com.controller.AdminController</managed-bean-class>
          <managed-bean-scope>request</managed-bean-scope>
          <managed-property>
               <property-name>adminbean</property-name>
               <property-class>com.model.AdminBean</property-class>
               <value>#{adminbean}</value>
         </managed-property>
     </managed-bean>
     <managed-bean>
          <managed-bean-name>adminbean</managed-bean-name>
          <managed-bean-class>com.model.AdminBean</managed-bean-class>
          <managed-bean-scope>request</managed-bean-scope>
          <managed-property>
               <managed-property>
               <property-name>admin</property-name>
               <property-class>com.model.Administrator</property-class>
               <value>#{admin}</value>
                         </managed-property>
     </managed-bean>     My JSP:<h:outputLink id="ol1" value="/companyadmin/copyusers.jsp">
           <h:outputText id="ot1" value="Copy Users" rendered="#{adminbean.admin.isGSA}" /><f:verbatim><br/></f:verbatim>
           </h:outputLink>    so now the issue is thelink copy users is displayed even #{adminbean.admin.isGSA} is FALSE. please advise.
Thanks
