passing parameter from one page to another page in JSF - jsf-2

Question

i am little bit stuck in my problem. i have sent the parameter from one xhtml page to another xhtml page successfully and i printed that parameter on my next page xhtml like this, #{param['id']}, but the problem is my #postConstructor is not executing, because i want that whenever my next page loads the parameter id sends over to database and get the required details in my datatable.
here is my code snippet of xhtml page from where i am sending parameters
<h:column>
<f:facet name="header">
Title
</f:facet>
<h:link value="#{item.title}" outcome="showObj.xhtml">
<f:param name="pid" value="#{item.id}" />
</h:link>
</h:column>
and here is my managedBean
package mb;
import java.io.Serializable;
import java.util.Map;
import javax.annotation.PostConstruct;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import javax.faces.bean.RequestScoped;
import javax.faces.bean.SessionScoped;
import javax.faces.context.FacesContext;
#ManagedBean(name="next")
#RequestScoped
public class showObj implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
#ManagedProperty(value="#{param.pid}")
private String name;
public String getName() {
System.out.println("in getter"+name);
return name;
}
public void setName(String name) {
this.name = name;
}
#PostConstruct // this will execute init() after id is injected
public void init() {
System.out.println("in init");
}
}
and here is my next xhtml page content, where i am receiving parameters.
<h:outputText value="#{param['pid']}"></h:outputText>
now i want that whenever my this parameter is received here, on page loading this parameter should send to database (the other ejb project). i know that if my #postConstructor runs than i can achieve this thing. but my #postConstructor is not executing.
i have also searched my problem over internet, they all says something about mojarra version, so i let you know that i have 2.1.6 version
