Description

I get the following:

java.lang.NullPointerException
at org.apache.tuscany.sca.core.databinding.transformers.Input2InputTransformer.transform(Input2InputTransformer.java:127)
at org.apache.tuscany.sca.core.databinding.transformers.Input2InputTransformer.transform(Input2InputTransformer.java:46)
at org.apache.tuscany.sca.databinding.impl.MediatorImpl.mediate(MediatorImpl.java:73)

when invoking a method such as:

public Person getGreetings()

where Person is an SDO causing the SDO databinding to be set at the impl DB level, and where I am using the WS binding, causing AXIOM to be used as the target DB.

I'll attach a simple patch to check for null first in the unwrapped->wrapped case in which the problem occurs.
