Frank Budinsky commented on TUSCANY-1084:
-----------------------------------------
Re: the point about serialization/deserialization only working in the
global/default scope. That's a current limitation. I guess you should open a
JIRA for it.
Maybe you want to implement it and also provide a patch? It's simply a matter
of adding an SDOUtil.createObjectInputStream(HelperContext) method that returns
a stream that also stores the context that was provided Then
ResolvableImpl.readDataObject() should be changed to use the XMLHelper from
that streams context, instead of the default one. The test program would be
changed to get the input stream from the new SDOUtil method.

>
> When a DataObject is serialized using the java serialization (
> ObjectOutputStream.writeObject) and deserialized back using
> ObjectInputStream.readObject, the types of the two dataobjects do not match,
> even though this all in the same scope ( global in this case ).
> During deserialization, it seems that the type of the dataobject cannot be
> found, and it is creating the type again and simply overwrites the previously
> registered type. This results in the dataobjects getting different types and
> the test case fails.
> There is another issue here, which is that currently there seems to be no way
> to provide a scope when using these java serialization methods. For instance,
> when using XMLHelper, you can get a scope defined XMLHelper. But how do you
> do this when you are using the java serialization methods ? If you want me to
> open another Jira for this i will.
