Table with composite key created only with specific prop order

[brezinajn]

object Foo: IdTable<Long>(){
    val bar = integer("bar").primaryKey()
    override val id: Column<EntityID<Long>> = long("id").entityId().autoIncrement().primaryKey()
}

This table produces crash on creation
org.jetbrains.exposed.exceptions.ExposedSQLException: java.sql.SQLSyntaxErrorException: Incorrect table definition; there can be only one auto column and it must be defined as a key

Simple solution is to switch the order of props:

object Foo: IdTable<Long>(){
    override val id: Column<EntityID<Long>> = long("id").entityId().autoIncrement().primaryKey()
    val bar = integer("bar").primaryKey()
}

Now the table creation goes smoothly.
Although there are situations where this workaround is not applicable (e.g. defining bar in abstract class and id in its child)

Looks like a bug. As a workaround you can add index explicitly to primaryKey():

object Foo: IdTable<Long>(){
    val bar = integer("bar").primaryKey(2)
    override val id: Column<EntityID<Long>> = long("id").entityId().autoIncrement().primaryKey(1)
}
