Dear Qi4j developers,
I'm trying to add SideEffects to Properties of Composites so that I can
trace getting and setting of property values. In order to get a feeling
for Qi4j in general (I'm a Newbie) and SideEffects in particular, I
copied LogPropertyAccess and LogPropertyChanges from
org.qi4j.runtime.property.PropertyTest together with the Company and Co.
composite to my test application:
public interface Company extends Nameable, TransientComposite {
}
@SideEffects({ LogPropertyAccess.class, LogPropertyChanges.class })
public interface Nameable {
Property<String> name();
}
Unfortunately, getting/setting property name() did not trigger the
expected SideEffects.
Applying the SideEffects directly to the property method did not work
either:
public interface Nameable {
@SideEffects({ LogPropertyAccess.class,
LogPropertyChanges.class })
Property<String> name();
}
The @Ignore comment on org.qi4j.runtime.property.PropertyTest ("This is
an incorrect satisfiedBy case. [...]") seems to indicate that
SideEffects on Properties might not work right now.?
If this is the case, is there another Qi4j-ish way to get notified about
property value changes? I'm intending to update UI elements whenever the
underlying Composites change state.
P.S. I also tested Concerns for Properties (instead of SideEffects);
this did not work either. But concerns on ordinary (non-property)
methods works find of course.
Many thanks,
Frank
