> Fix deserialization for new fields in PdxSerializable class
> -----------------------------------------------------------
>
> Key: GEODE-9968
> URL: https://issues.apache.org/jira/browse/GEODE-9968
> Project: Geode
> Issue Type: Bug
> Components: native client
> Reporter: Mario Salazar de Torres
> Assignee: Mario Salazar de Torres
> Priority: Major
> Labels: needsTriage
>
> *GIVEN* an implementation of a PdxSerializable class
> *WHEN* a set of entries have been written for this class
> *AND* after a while, the implementation changes, adding new fields
> *AND* a new set of entries are written containing some of the added fields
> *AND* all of the region entries are read
> *THEN* added fields of the latest entries are empty or contain garbage instead
> ----
> *Additional information.* After analyzing Java implementation for
> PdxSerializable deserialization, it seems that the client fetches the
> PdxFields from the remote PdxType, but instead for the C++ implementation,
> code is different as it uses a mapping called "Local2Remote" (which I suppose
> it's an optimization). And the current use of this "Local2Remote" mapping is
> not working correctly under the described scenario.
