Summary of bug description * Actual behavior: Modules cannot properly register properly their file readers and writers in order to provide their on file format * expected behaviour: CoreObjectFactoryBase should provide a mechanism to register factories. Cause of the bug (How could this happen?, what went wrong?) - does not apply here Proposed solution (How do I plan to fix this? Other solutions?) - see attachment Affected classes (Which classes will be modified?) - mitk/Core/Code/Algorithms/mitkCoreObjectFactory.cpp - mitk/Core/Code/Algorithms/mitkCoreObjectFactory.h - mitk/Core/Code/Algorithms/mitkCoreObjectFactoryBase.h How will the bugfix get tested? (unit test possible?, manual test necessary? how can it be tested?) - is the CoreObjectFactory subject of unit testing yet?
