I wrote a pretty simple transform worker and when I changed its name
all my events quit working.
After a bit of debugging I tried adding after:* to the configuration
and they work again
configuration.add("NVLWorker", new NVLWorker(nvlService),"after:*");
If I change to
configuration.add("NVLWorker", new NVLWorker(nvlService),"before:*");
They stop.
The worker does mess with events but I'm not sure what I'm doing that
would stop all events
public class NVLWorker implements ComponentClassTransformWorker2 {
private NVLService nvlService;
private final String id = NVLWorker.class.getName();
public NVLWorker(NVLService nvlService) {
this.nvlService = nvlService;
}
public void transform(PlasticClass plasticClass, TransformationSupport
support,
MutableComponentModel model) {
List<PlasticField> fields =
plasticClass.getFieldsWithAnnotation(NVL.class);
for ( PlasticField field : fields ) {
if ( nvlService.isImplemented(field.getTypeName())) {
support.addEventHandler(EventConstants.PREPARE,0,"Init if null",
createPrepareHandler(field.getTypeName(), field.getHandle()));
}
}
}
private ComponentEventHandler createPrepareHandler(final String
typeName, final FieldHandle handle) {
return new ComponentEventHandler() {
public void handleEvent(Component component,
ComponentEvent event) {
if ( handle.get(component) == null ) {
handle.set(component,
nvlService.newInstance(typeName));
}
}
};
}
}
The page contains
@PageActivationContext
@Property
@NVL
private IPerson person;
void onActivate() {
if ( person == null ) {
logger.info("person is null");
}
}
void onSuccess() {
logger.info("age {}" , person.getAge());
}
with after:* both onActivate and onSuccess are called. With before:*
neither is called. I'm OK with added after:* but I don't really
understand why that fixes it. Any help would be appreciated. FYI I'm
running 5.3-beta-13
Thanks
Barry
