Use of version metadata is misleading and leading to errors when handling inherited classes with versions

Created: 13/Jul/11 07:46 PM   Updated: 01/Aug/11 10:23 AM   Resolved: 13/Jul/11 08:58 PM
Component/s: MetaData
Affects Version/s: 2.0.5, 2.1.4, 2.2.4, 3.0.0.m6
Fix Version/s: 3.0.0.release

 Description  « Hide
In AbstractClassMetaData we have "hasVersionStrategy" (which checks if this class itself has defined a strategy), and "getVersionMetaData" (which just returns the metadata defined for this class). Obviously if a superclass exists and defines the metadata for versioning then it should be used (since this one will be null). The majority of store plugins get it wrong and just use this class' metadata. We should remove misleading methods and update store plugins to use the correct method(s)
