Transform nullable columns

[catsuperberg]

If nullable properties are allowed in Entity and databases overall support null fields, why wouldn't transform method be able to accept null from fromUnderlyingValue. IDK maybe i'm doing something wrong but i have serializable FloatRange class and as a field for it isn't essential i would prefer to get null on failed serialization. As it is now i can't find any other option but use some default value or split range into two columns for min and max.

I use it like so:

val range = varchar("range").transform(
     { FloatRange.parseFromString(it) ?: FloatRange(0f, 0f) }, { it.toString() }
).bindTo { it.range }
