Hi Erik,
Pretty sure this is all working in 1.6.0; in fact the changes you've made
are (coincidentally?) also part of the todoapp app, as generated by the
todoapp-archetype;
mvn archetype:generate \
-D archetypeGroupId=org.apache.isis.archetype \
-D archetypeArtifactId=todoapp-archetype \
-D archetypeVersion=1.6.0 \
-D groupId=com.mycompany \
-D artifactId=myapp \
-D version=1.0-SNAPSHOT \
-B
If you run the above and import into your IDE, then you can set a
breakpoont on ToDoItemSubscriptions and see it invoked.
@Programmatic
@Subscribe
public void on(PropertyInteractionEvent<?,?> ev) {
recordEvent(ev);
switch(ev.getPhase()) {
...
case EXECUTED:
LOG.info("Received PropertyInteractionEvent, " +
container.titleOf(ev.getSource()) + ", changed " +
ev.getIdentifier().getMemberName() + " : " + ev.getOldValue() + " -> " +
ev.getNewValue());
...
break;
}
}
Or, just look at the console:
06:47:51,939 [ToDoItemSubscriptions 1177678328@qtp-1850527708-1 INFO ]
Received PropertyInteractionEvent, Buy milk xxx due by 2014-09-30, changed
description : Buy milk -> Buy milk xxx
~~~~~~~~~~
For your example, the reason why the event is fired when rendered is
because that will be the hidden phase. In fact, it should be fired twice,
once for hidden phase, once for disabled. This allows subscribers to veto
the visibility/enablement of any given class member being rendered.
