Issue Kind (Bug, Question, Feature): Bug

Description: Type Converter Bug

import com.raizlabs.android.dbflow.converter.TypeConverter;
import com.raizlabs.android.dbflow.data.Blob;

@com.raizlabs.android.dbflow.annotation.TypeConverter
public class BlobConverter extends TypeConverter<Blob, byte[]> {


    @Override
    public Blob getDBValue(byte[] model) {
        return model == null ? null: new Blob(model);
    }

    @Override
    public byte[] getModelValue(Blob data) {
        return data == null ? null: data.getBlob();
    }
}

import com.raizlabs.android.dbflow.converter.TypeConverter;
import com.raizlabs.android.dbflow.data.Blob;

@com.raizlabs.android.dbflow.annotation.TypeConverter
public class BlobConverter extends TypeConverter<Blob, byte[]> {


@Override
  public final void bindToInsertStatement(DatabaseStatement statement, Conversation model,
      int start) {
    statement.bindStringOrNull(1 + start, model.getUuid());
    statement.bindStringOrNull(2 + start, model.getName());
    statement.bindLong(3 + start, model.getPhoneNo());
    statement.bindLong(4 + start, model.getStatus());
    **Blob refseed = model.getSeed() != null ? typeConverterBlobConverter.getDBValue(model.getSeed()) : null;
    statement.bindBlobOrNull(5 + start, refseed.getBlob());**
    Blob refprivateKey = model.getPrivateKey() != null ? typeConverterBlobConverter.getDBValue(model.getPrivateKey()) : null;
    statement.bindBlobOrNull(6 + start, refprivateKey.getBlob());
    Blob refpublicKey = model.getPublicKey() != null ? typeConverterBlobConverter.getDBValue(model.getPublicKey()) : null;
    statement.bindBlobOrNull(7 + start, refpublicKey.getBlob());
    statement.bindLong(8 + start, model.getKeyValidity());
  }

Here Auto generated method not checking where Blob is null or not (Check bold line)
statement.bindBlobOrNull(5 + start, refseed.getBlob());

Its giving null pointer exception when tying to save the data

    @Column( typeConverter = BlobConverter.class, name = "key_seed")
    private byte[] seed;

need more info. like what your model class looks like. have you tested with 4.0.5 yet?

The pull request I just submitted I think fixes this. An alternative is to just use the dbflow Blob type in the model instead of a byte array directly (a dbflow Blob just wraps the byte array).

in develop for 4.1.1
