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();
}
