Thanks Stan, I missed that discussion. I checket open issues in Jira, but I
don't think my issue is related to Qi-272 or Qi-274, but I might be mistaken...
Isn't
Property<String> someString();
regarded as a method needing an implementation (by Qi4j though) causing the
implementing Mixin to be included in the composite? I'm confused and could well
be mixing up terms.
Shouldn't it be possible to have an entity with only Properties and a
Lifecycle??
Now I had to make a dummyMethod() in my entity interface and a dummy
implementation in the Mixin in order for the Lifecycle to work. Seems wrong,
when there's several Properties in use already, and some of them needs to be
set upon entity creation...
Cheers,
Marc
