• [ Mantis 123 ] Renamed parameter to EcoSpacePart.Serialize from "source" to "target" to better indicate what it is used for...
• [ Mantis 272 ] Balanced the ocl parse-tree while building it to avoid getting too deeply nested trees with expressions like (x=1) or (x=2) or (x=3) or (x=4) ... or (x=n). Only applied for commutative operations (where (x op (y op z)) is equivalent to ((x op y) op z), and only if the expression is not explicitly parenthesised.
• [ Mantis 230 ] PersistenceService now ignores objects that have been created and deleted again before they are sent to UpdateDatabase
• OCL-editor now shows non-navigable association ends too. They are allowed in OCL.
