[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-583) EL MethodExpression fails to find overloaded methods properly

EL MethodExpression fails to find overloaded methods properly ------------------------------------------------------------- Key: JBSEAM-583 URL: http://jira.jboss.com/jira/browse/JBSEAM-583 Project: JBoss Seam Issue Type: Bug Components: JSF Affects Versions: 1.1.0.CR1 Environment: JBoss 4.0.5.GA, 64-bit 1.5 VM, Apache MyFaces 1.1, Facelets Reporter: Jasper Bryant-Greene We have the following SLSB: <code> @Stateless @Name("admin.clientManager") @Scope(ScopeType.SESSION) public class ClientManagerAction implements ClientManager { @In @Out private Client client; public String view() { return "/j/admin/client.xhtml"; } public String view(Client client) { this.client = client; return view(); } public Client getClient() { return client; } public void setClient(Client client) { this.client = client; } } </code> We try to call the overloaded view(Client client) method from a view as follows: <s:link action="#{admin$clientManager.view(domain.client)}" value="#{domain.client.firstName} #{domain.client.lastName}" /> JSF seems to not find the overloaded method, and instead throws this exception: 2006-12-13 15:33:41,246 ERROR [org.apache.myfaces.lifecycle.PhaseListenerManager] Exception in PhaseListener RENDER_RESPONSE(6) beforePhase. javax.faces.el.EvaluationException: No method found for expression #{admin$clientManager.view(domain.client)}.
