h:commandLink with f:param

Question

Hello, I've got a simple list of commandLinks and
I try to add a parameter to them
               <c:forEach items="#{BrowserMB.categories}" var="abc">
                    <h:form>
                         <h:commandLink action="#{BrowserMB.browse}">
                              <h:outputText value="#{abc}" />
                              <f:param name="c" value="#{abc}" />
                         </h:commandLink>
                    </h:form>
               </c:forEach>Here's the part of managedBean class
     private String c = "asd";
     public String browse() {
          products = (getKatalogBean().getProductsByCategory(c));
          setPrepared(true);
          return "result";
     public String getC() {
          return c;
     public void setC(String c) {
          this.c = c;
     }but the problem is that the property "c" never gets updated, the method
getProductsByCategory(c)is always called with the default value. Do you know why?
Thanks for answering.

You need to either replace f:param by f:propertyActionListener as outlined here, or to define the parameter as managed property in faces-config.xml as outlined here.
