[Simple-support] Exception when using @version on derived class (on Android)

[Mogens H. <mo...@hv...>]

I have a base class that is serialized (but has no version attribute):

@Root
public abstract class BaseLayerType implements ILayerType {
	
	@Element
	private Plate plate;
        .....


And a derived class that where I have added an version member with the
@Version attribute

@Root
public class PrimCollLayerType extends BaseLayerType {
	
	@Version(revision=1.1)
	private double version;

	@Element
	int primType = PrimCollLayerData.PRIMITIVE_TAG;
        ....


This will cause following exception when I deserialize:

07-23 20:26:55.240: ERROR/ColonyCount(23073): java.lang.NullPointerException
