Exposed-money: can't access currency and amount for nullable compositeMoney columns

object Article : IntIdTable() {
  val name = varchar("name", 100).nullable()
  val price = compositeMoney(10, 5,"price").nullable()
}

cant reference the amount and currency : Article.price.amount because nullable() here returns CompositeColumn and not CompositeMoneyColumn

As a workaround we can do a cast:

object Article : IntIdTable() {
  val name = varchar("name", 100).nullable()
  val price = compositeMoney(10, 5,"price").nullable() as CompositeMoneyColumn<BigDecimal?, CurrencyUnit?, MonetaryAmount?>
}

Same thing for default() method

I suggest to make improvement so that we can manage better compositeMoney columns. @Tapac , any thoughts?

I’ve run into this as well and also used casting to fix the issue. The issue is here, where we cast the column as nullable, thereby losing the composite typing. @hfazai I have this:

typealias NullableMoneyColumn = CompositeMoneyColumn<*, *, MonetaryAmount?>

so you can do as NullableMoneyColumn. I also recall the nullable generics on the composite money column being inconsistent, like sometimes you can put in nulls but not take them out or vice versa.

@jnfeinstein , thank you for the idea. That sounds like a plan. I will try to extend the CompositeColumn class with default implementation,
