[jboss-user] [JBoss Seam] - trouble with h:commandLink and f:param...

[holtak]

hello

My .xhtml looks like this:

  | <f:facet name="Criterion">
  |             <h:panelGroup>
  |             	<h:commandLink action="input_rating"  actionListener="#{t.setNodeSelected}">
  |                		<t:graphicImage value="/img/icons/16x16/actions/jabber_online.png"/>
  |                 	<h:outputText value="#{node.description}" styleClass="nodeFolder"/>
  |                 	<h:outputText value=" #{node.rating}"/>
  |                 	<f:param name="ratingCriterionParId" value="#{node.identifier}"/>
  |                 </h:commandLink>
  |             </h:panelGroup>
  |         </f:facet>
  | 

navigation.xml contains:

  | <navigation-case>
  |          <from-outcome>input_rating</from-outcome>
  |          <to-view-id>/rate/inputRating.xhtml</to-view-id>
  |          <redirect />
  | </navigation-case>
  | 

then I have a file called inputRating.page.xml:
<!DOCTYPE pages PUBLIC
  |   "-//JBoss/Seam Pages Configuration DTD 1.2//EN"
  |   "http://jboss.com/products/seam/pages-1.2.dtd">
  | <page action="#{inputRatingAction.loadRatingCriterion(param.ratingCriterionParId)}">
  | 	<description>Rating category #{ratingCriterion.name}</description>
  | 	<begin-conversation join="true" />
  | </page>

and finaly InputRatingActionImpl.java which contains:
public RatingCriterion loadRatingCriterion(Object id) {
  | 		if(id!=null){
  | 			ratingCriterion = ratingCriterionHome.find(id);
  | 		}
  | 		return ratingCriterion;
  | 	}

My problem is, that the id - parameter of loadRatingCriterion always gets a null value and I trully don`t know why...

When I switch to s:link all works fine, but I must submit the form.

thanks...
