BREAKING CHANGE

systems.dmx.core.ChildTopics

remove the 4 addRef() methods:

ChildTopics addRef(String compDefUri, long refTopicId);
ChildTopics addRef(String compDefUri, long refTopicId, ChildTopicsModel relatingAssocChildTopics);
ChildTopics addRef(String compDefUri, String refTopicUri);
ChildTopics addRef(String compDefUri, String refTopicUri, ChildTopicsModel relatingAssocChildTopics);

CODE TRANSFORMATION

Instead of

    topic.getChildTopics().addRef(compDefUri, ...);

write

    topic.update(mf.newChildTopicsModel().addRef(compDefUri, ...));
