Your syntax is incorrect. This line should be:
f = new Foo.from (1);
The way you have written it, vala thinks Bar inherits from Foo. In the
case where you call a base constructor, this will indeed be null until
you call the base constructor.
public class Foo
{
int i;
public Foo.from(int i)
{
this.i = i;
}
}
public class Bar : Foo
{
public Bar()
{
assert( this != null ); // fails because `this` really is null here
base.from(1);
assert( this != null ); // succeeds
}
}
int main(string[] argv)
{
var b = new Bar();
return 0;
}
