I finally did not touch anything in the PortletDataContextImpl, the problem that I was having is that, in the conversion from the element to the model in PortletDataContextImpl is managed by the StagedModelDataHandlerUtil, and it just take the path from the element where the object is located  and it uses that model to call the importStagedModel method again. What I have done is to retrieve myself such model, modify the classPK and call the importStagedModel passing the modified model.
