One last question please: Is the custom Dialect with ...

1 and 0 is the default behavior for the boolean type. Just make your properties boolean or Boolean (if you have tri-state behavior). If you're silly like us then you would have to specifically set the type if you wanted to use something like Y/N. Or you could write your own type and map to Bob and Doug ;)
