[jboss-user] [EJB/JBoss] - Seam 2: EL and anonymous classes

1. I'm using the Seam2 beta with JBoss 4.2 and I am having a problem with the following expression.
Expression
| <h:commandButton id="select" value="Select" action="#{organizationEditor.select}"
| class="primary"
| rendered="#{not empty partyFinderClient and partyFinderClient.supportsSelect}"/>
|
When the expression is evaluated it throws an IllegalAccessException (see bottom). The class is anonymous, the method is public and also overrides an abstract method. Is there a reason that i cannot access methods on an anonymous class using EL?
2. Where can I get the source for jboss-el.jar? This lib is distributed with the source for JBoss 4.2 and Seam 2. I can't seem to find it among the JBoss projects.
Thanks
Richard
PartyFinderClient
| public abstract class PartyFinderClient {
|
|
| private static final String PARTY_FINDER_CLIENT = "partyFinderClient";
|
| public static void clear() {
| Contexts.getConversationContext().set(PARTY_FINDER_CLIENT, null);
| }
|
| public void install() {
| Contexts.getConversationContext().set(PARTY_FINDER_CLIENT, this);
| }
|
| public static PartyFinderClient getInstalled() {
|
| return (PartyFinderClient) Contexts.getConversationContext(). get(PARTY_FINDER_CLIENT);
| }
|
| public abstract boolean supportsCancel();
| public abstract boolean supportsSelect();
| public abstract String cancel();
| public abstract String select(Party party);
| public abstract SearchStrategy getStrategy();
| }
|
Typical subclass
| @Begin(flushMode=FlushModeType.MANUAL, join=true)
| public void findPersons() {
| PartyFinderClient client = PartyFinderClient.getInstalled();
| if (client == null) {
| client = new PartyFinderClient() {
|
| public String cancel() {
| return null;
| }
|
| public String select(Party person) {
| //Hack. Because this is being called from PartyFinder, the "registration" component is not being injected?
| Contexts.getConversationContext().set("person", person);
| return "/forms/party/person/identity";
| }
|
| public SearchStrategy getStrategy() {
| return new FindPersonStrategy();
| }
|
| @Override
| public boolean supportsCancel() {
| return false;
| }
|
| @Override
| public boolean supportsSelect() {
| return false;
| }
|
| };
| client.install();
| }
| find();
| }
