[jbossseam-issues] [JBoss JIRA] Created: (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:
@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;
}
}
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)}. Method name and number of params must match.

[snip]
I will take a look at the code tonight, it looks fairly simple and I may be able to come
up with something.
