cannot save the svm model

I have imported the SVM classification model learned in classification app. I have tried both of the codes below to save it but I get error. What is the probelsm?

saveLearnerForCoder(trainedSVMModel.ClassificationSVM, 'modelSVM');
saveCompactModel(trainedSVMModel.ClassificationSVM) 

Here is the error I get for both of them:

Reference to non-existent field 'ClassificationSVM'.

Error in ex (line 5)
saveLearnerForCoder(trainedSVMModel.ClassificationSVM, 'modelSVM')
