Passing hidden Input to backing bean

[vishnu bola]

I have a problem passing a hiddenInput to a backing bean and need your help.

 <t:dataTable id="groupuserlist"
	         var="user"	        
                         value="#{manageuserscontroller.userList}"
                      cellspacing="0"
             preserveDataModel="false"
             headerClass="topRow"
             summary="This table displays list of users for an accessgroup">
     <t:column>
      
      <f:facet name="header">
      <t:panelGroup>
      <t:commandSortHeader columnName="lastname" arrow="true"><t:outputText value="Last Name"/></t:commandSortHeader>
      <f:verbatim><br /></f:verbatim>
      <t:commandSortHeader columnName="firstname" arrow="true"><t:outputText value="First Name"/></t:commandSortHeader>
       
       
      </t:panelGroup>
   </f:facet>


      <h:outputLink styleClass="tips" value="popup.jsp#moreinfo"  title="#{user.lastName} #{user.firstName}" ><t:outputText value="more info..." />
       </h:outputLink>
     
            
     <h:inputHidden id="userID" value="#{user.ID}" />
 

     </t:column>
        

 <f:view> 


<div> 
<div id="moreinfo">
	<div class="coAdminPopup">
			
            <t:saveState value="#{manageuserscontroller.userObj}" />
		<table cellspacing="0" class="marTopLrg">
			<caption class="accessibility">Email address, Phone number and Mailing Address</caption>
			<tr>
				<th scope="row">Email:</th>
				<td><t:outputText value="#{manageuserscontroller.userObj.email}" /></td>
			</tr>   

</table>

</div>
</div>
</f:view>

I want to pass the current userID to a managed bean property called userID.

   public class ManageUsersController {
private String userID;
 public void setUserID(String userID) {
	    this.userID=userID;
    } public String getUserID(){
        return userID;
   	}
public UserImpl getUserObj() {
  
     
    		loadUserObj();
  	
  	return userObj;
    }

 public void loadUserObj() {
System.out.println("userid from facescontext" + FacesContext.getCurrentInstance().getExternalContext()
	            .getRequestParameterMap().get("userID"));
}
 

When i print this statement i get null in my userID. Can someone help me why i am not able to pass the hiddenInput to the backing bean?

code] <managed-bean>
<managed-bean-name>manageuserscontroller</managed-bean-name>
<managed-bean-class>com.forrester.companyadmin.controller.ManageUsersController</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>

</managed-bean>[ [/code]
