Hello!

Can someone tell me how to catch parameters passed from URI in JSF's managed bean? I have a navigation menu all nodes of which link to some navigation case. And i have two similar items there: Acquiring products and Issuing products. They have the same page but one different parameter: productType. I try to set it just by adding it to URL in "to-view-id" element like this:

<navigation-case>
    <from-outcome>acquiring|products</from-outcome>
    <to-view-id>/pages/products/list_products.jspx?productType=acquiring</to-view-id>
</navigation-case>

<navigation-case>
    <from-outcome>issuing|products</from-outcome>
    <to-view-id>/pages/products/list_products.jspx?productType=issuing</to-view-id>
</navigation-case>

But i can't get this "productType" from my managed bean. I tried to get it through FacesContext like this:

FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("productType")

And like this:

HttpServletRequest request = (HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest();
    request.getParameter("productType");

And i tried to include it as a parameter of managed bean in faces-config.xml and then getting it through ordinary setter:

 <managed-bean>
        <managed-bean-name>MbProducts</managed-bean-name>
        <managed-bean-class>my.package.product.MbProducts</managed-bean-class>
        <managed-bean-scope>request</managed-bean-scope>
     <managed-property>
         <property-name>productType</property-name>
         <value>#{param.productType}</value>
     </managed-property>
    </managed-bean>
...
public class MbProducts {
...
 public void setProductType(String productType) {
  this.productType = productType;
 }
...
}

But neither of these ways have helped me. All of them returned null. How can i get this productType? Or how can i pass it some other way?
