[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-2571) Event observers in overridden components are still being invoked
[ http://jira.jboss.com/jira/browse/JBSEAM-2571?page=comments#action_12399015 ]
Sebastien Degardin commented on JBSEAM-2571:
--------------------------------------------
Another options, which could be more interesting would be to not process any overriden
field or method.
In the method below, we could call a Reflection utility method like
"isMethodOverridden(Method method, Class componentClass)"
So that we would know if we have to process such a method.
Here is an example of such solution in ( class org.jboss.seam.Component ) :
for (Class superClass = clazz ; superClass!=Object.class; superClass =
superClass.getSuperclass() )
{
for ( Method method: superClass.getDeclaredMethods() )
{
if (! Reflections.isMethodOverriden(method, clazz))
{
scanMethod(applicationContext, selectionSetters, dataModelNames, method);
}
}
}
Event observers in overridden components are still being invoked
----------------------------------------------------------------
Key: JBSEAM-2571
URL: http://jira.jboss.com/jira/browse/JBSEAM-2571
Project: JBoss Seam
Issue Type: Bug
Components: Core
Affects Versions: 2.0.1.GA
Reporter: Shane Bryzak
Assigned To: Shane Bryzak
Priority: Blocker
Fix For: 2.0.2.GA
When overriding a built in component and providing a new observer, the observer in the
overridden component is still registered and both observers are invoked upon the event.
Here is a test case provided by a user that reproduces this issue:
@Name("org.jboss.seam.security.facesSecurityEvents")
@Scope(ScopeType.APPLICATION)
@Install(precedence = Install.APPLICATION, classDependencies =
"javax.faces.context.FacesContext")
@BypassInterceptors
@Startup
public class SecurityEventsHandler extends org.jboss.seam.security.FacesSecurityEvents {
@Logger Log log;
@Override @Observer(Identity.EVENT_LOGIN_SUCCESSFUL)
public void addLoginSuccessfulMessage()
{
log.info("\n\n\n>>>>>>>>>>>>>>>>>>>>EVENT_LOGIN_SUCCESSFUL
handled<<<<<<<<<<<<<<<<<<<<<<<<\n\n\n");
}
}
