New processing for stateful bean @Destroy and @Remove causes problems.
----------------------------------------------------------------------
Key: JBSEAM-1593
URL: http://jira.jboss.com/jira/browse/JBSEAM-1593
Project: JBoss Seam
Issue Type: Bug
Components: Core
Affects Versions: 2.0.0.BETA1
Reporter: Chris Rudd
I have an EJB that has several methods marked as @Remove, as I want the bean remove whenever those methods are executed.
One of which is marked as @Destroy, which is the ONLY one that should be called because the object is being destroyed (ie from a call to Component.destroy. The problem is that under the new processing rules the "defaultRemoveMethod is set to the last parameterless @Remove method.
I would suggest that the defaultRemoveMethod only be set to a "found @Remove" method if the @Destroy method has not been defined / does not have the @Remove annotation.
my class :
class Foo {
@Destroy
@Remove
public void cleanup() { /* does state cleanup*/ }
@Remove
public String removeEntity() { /* does some work*/ }
}
For this class cleanup is executed because its the destroy method, then removeEntity is executed since it was the last @Remove method found.

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-1602) exception handler not recognizing end-conversation

exception handler not recognizing end-conversation
--------------------------------------------------
Key: JBSEAM-1602
URL: http://jira.jboss.com/jira/browse/JBSEAM-1602
Project: JBoss Seam
Issue Type: Bug
Components: Core
Affects Versions: 2.0.0.BETA1
Environment: Seam-CVS
Reporter: Hung Tang
In my application, I'm using pages.xml exception handling mechanism to automatically end conversations when optimistic locking exceptions ever arise.
This is what I have
<exception class="javax.persistence.OptimisticLockException">
<end-conversation/>
<redirect view-id="/p/home.xhtml">
<message severity="ERROR">#{messages['concurrentmodification']}</message>
</redirect>
</exception>
However, when it does come up, the conversation is not ending as I want.
I could reproduce this error in the contact-list example. Just add begin propagation to the editContact and the exception handler will recognize it as a javax.persistence.PersistenceException, but it will not end the conversation as you have told it to.

[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-1584) @Logger and Spring beans

@Logger and Spring beans
------------------------
Key: JBSEAM-1584
URL: http://jira.jboss.com/jira/browse/JBSEAM-1584
Project: JBoss Seam
Issue Type: Feature Request
Components: Spring
Affects Versions: 2.0.0.BETA1
Reporter: Magnus Heino
It would be nice if spring beans could be scanned for @Logger and injected with Log instances just like seam components.
Using the code below, you can add this to applicationContext.xml...
<bean class="org.jboss.seam.ioc.spring.LoggerPostProcessor" />
...to have all spring beans scanned for @Logger and have a Log instance injected, just like seam components. Then you can access the same context and log functionallity in your spring beans as in your seam components.
I guess the seam spring namespace could be extended with <seam:logger/> to make it even more simple to use.
package org.jboss.seam.ioc.spring;
import java.lang.reflect.Field;
import org.jboss.seam.annotations.Logger;
import org.jboss.seam.log.Logging;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.BeanPostProcessor;
import org.springframework.util.ReflectionUtils;
import org.springframework.util.StringUtils;
import org.springframework.util.ReflectionUtils.FieldCallback;
public class LoggerPostProcessor implements BeanPostProcessor {
public Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException {
return bean;
}
public Object postProcessBeforeInitialization(final Object bean, final String beanName) throws BeansException {
ReflectionUtils.doWithFields(bean.getClass(), new FieldCallback() {
public void doWith(Field field) throws IllegalArgumentException, IllegalAccessException {
if (field.isAnnotationPresent(Logger.class)) {
String category = field.getAnnotation(Logger.class).value();
if(!StringUtils.hasText(category)) {
category = bean.getClass().getName();
}
ReflectionUtils.makeAccessible(field);
field.set(bean, Logging.getLog(category));
}
}
});
return bean;
}
}
