ChangeSet analysis fails with unversioned types

PersistencyLayer

The ChangeSetAnalyzer is used to analyze a KnowledgeBase ChangeSet and turn it into a model ChangeSet, which is then displayed to the user in the application as a functional log.

If one of the functional object types is not versioned, a NullPointerException is thrown when analyzing the object creation:

java.lang.NullPointerException: Cannot invoke "com.top_logic.knowledge.objects.KnowledgeItem.getWrapper()" because the return value of "com.top_logic.element.changelog.ChangeSetAnalyzer.resolve(com.top_logic.dob.identifier.ObjectKey)" is null at com.top_logic.element.changelog.ChangeSetAnalyzer.analyzeCreations(ChangeSetAnalyzer.java:255) at com.top_logic.element.changelog.ChangeSetAnalyzer.analyze(ChangeSetAnalyzer.java:182) at com.top_logic.element.changelog.ChangeSetAnalyzer.hasChanges(ChangeSetAnalyzer.java:146) at com.top_logic.element.changelog.ChangeLogBuilder.readChanges(ChangeLogBuilder.java:366) at com.top_logic.element.changelog.ChangeLogBuilder.readChangesDescending(ChangeLogBuilder.java:333) at com.top_logic.element.changelog.ChangeLogBuilder.readDescending(ChangeLogBuilder.java:282) at com.top_logic.element.changelog.ChangeLogBuilder.build(ChangeLogBuilder.java:265) at test.com.top_logic.model.search.expr.TestSearchExpression.with(TestSearchExpression.java:2668)
