i have the same problem in a different way. The parameter passed to method is null.

i have a <s:link> in a dataTable :

<rich:dataTable value="#{genes}" var="gene" ....> ....
  | <s:link action="#{tableviewer.displayTargetSequences(gene)}"> ...</s:link>
  | .....</rich:dataTable>

tableviewer is stateless session bean for outjection the parameter and redirection.

  | @Name("tableviewer")
  | public class TableViewerAction implements ITableViewer{    
  | @Out private Gene selectedGene;
  | public TableViewerAction() {}
  | public String displayTargetSequences(Gene gene) {
  |         selectedGene = gene;
  |         return "/targetSequenceViewer.xhtml";
  |    }
  | }

This bean is used only here and constructed probably right after the user clicked on it. Is this the problem?
