Have you setup your migrations class?

i.e.

public class Migrations : DataMigrationImpl {

    public int Create() {
        SchemaBuilder.CreateTable("ProductRecord",
            table => table
                .ContentPartRecord()
                .COLUMNS NEED TO BE SPECIFIED
            );

        ContentDefinitionManager.AlterTypeDefinition("Forum",
            cfg => cfg
                .WithPart("ProductPart")
                .WithPart("CommonPart")
            );

Also have you setup your repository?

i.e.

public class ProductPartHandler : ContentHandler {
    public ProductPartHandler(IRepository<ProductPartRecord> repository) {
        Filters.Add(StorageFilter.For(repository));
    }
