Is it a Vala Bug?
When I test this code, there's no problem at runtime:
using Gee;
class Container : Object
{
public Gee.TreeMap<string,Object> map = new Gee.TreeMap<string,Object> ();
}
class Space : Object
{
public string name { get; set; }
public Space.named (string name) { this.name = name; }
}
class App : Object
{
public static int main (string[] args)
{
var c = new Container ();
var o1 = new Space.named ("Big");
var o2 = new Space.named ("Small");
c.map.set (o1.name, o1);
c.map.set (o2.name, o2);
foreach (Object o in c.map.values) {
stdout.printf (@"VALUE: $(((Space) o).name)\n");
}
foreach (string k in c.map.keys) {
stdout.printf (@"KEY: $(k) : VALUE: $(((Space) c.map.get
(k)).name)\n");
}
return 0;
}
}

Trabajar, la mejor arma para tu superación
"de grano en grano, se hace la arena" (R) (en trámite, pero para los
cuates: LIBRE)
