Secondary constructor in custom type

[Enrique Rodríguez]

I've recently created a class called IntId that extends Intfield
defined this way:

import org.squeryl.customtypes.CustomTypesMode._
import org.squeryl.customtypes.IntField

class IntId(value: Int) extends IntField(value) {

// some code about the domain of the id...

override def toString = value.toString

// and a secondary constructor:
def this(s: String) = this(IntId.parseInt(s))

}

object IntId {

def parseInt(s: String): Int = {
if (s.length > 0) s.toInt
else IntId.UNDEFINED
}

val UNDEFINED = -1

}

The problem is that, when Squeryl tries to select from the database an
object that uses IntId as field, it fails with a
java.lang.IllegalArgumentException.

java.lang.RuntimeException: could not map row :
ResultSetRow:[1:Integer,AR1828:String,...]
with mapper :
'ResultSetMapper:1c8b884($(1-
>Product.productId:org.banquinet.util.IntId),$(2-
>Product.abbreviation:org.banquinet.util.Abbreviation),...
...
Caused by: java.lang.RuntimeException:
Product.productId:org.banquinet.util.IntId was invoked with value '1'
of type java.lang.Integer on object of type
org.banquinet.sistaller.Product

And it's curious because it works perfect if I comment the secondary
constructor.
Isn't it possible to define secondary constructors in custom type
classes?

Thank you for your time.

Please create an issue : https://github.com/max-l/Squeryl/issues and could you also :

1) try this workaround : add a zero arg constructor to your class
2) send the complete stack trace

Thanks

I tried adding a zero arg constructor and got the same results.

Complete stack trace:

Now I've found that it works with a two or more args secondary
constructor.
I've looking the code and I think that maybe the problem is that, when
creating the custom type factory, it searches for a constructor with
one parameter.
