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.

@(protected)
| @(protected)("tableviewer")
| public class TableViewerAction implements ITableViewer{
| @(protected) 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?
