Statements and facets are both overridden in parallel use.

Actions:
user1: edit facet (or statement) xy
user2: edit same facet (or same statement) and save while other user still editing

Observation: facets/statements are overridden in parallel use, showing the following behaviour:

• Facet Name gets overridden
• Facet Select (Index) gets overridden
• Statement Name does NOT get overridden, but: An error message occurs "Error editing statement: Error deleting resource /statement/153. Resource doesn't exist!" -> And an additional Statement is created nevertheless!
• Statement Namespace gets overridden
• Statement Predefined values get overridden

Question: Should statements and facets be included to concurrency fixes?
