Solved Error with config list

Hello! I have an error when I try to get all the objects of a list in a config. I have this code:

Code (Java):

                    for(String generator : configc.getStringList("Generators.list")) {

                        Location loc = Main.getInstance().stringToLocation(world, configc.getString("Generators.list." + generator + ".loc"));
                        String type = configc.getString("Generators.list." + generator + ".type");
                        int level = configc.getInt("Generators.list." + generator + ".level");
                        Sign sign = (Sign) world.getBlockAt(Main.getInstance().stringToLocation(world, configc.getString("Generators.list." + generator + ".sign"))).getState();

                        gm.getGenerators().add(new Generator(loc, type, level, gm, sign));

                    }

The config is:

Code (YAML):

Generators:
  list:
    hola:
      loc: 5050.0 12.0 -29.0 0.0 0.0
      type: iron
      level: 1
      sign: 5050.0 13.0 -29.0 0.0 0.0
    holab:
      loc: 5043.0 12.0 -18.0 0.0 0.0
      type: iron
      level: 2
      sign: 5043.0 13.0 -18.0 0.0 0.0
    holac:
      loc: 5033.0 15.0 -30.0 0.0 0.0
      type: gold
      level: 1
      sign: 5033.0 16.0 -30.0 0.0 0.0
    holad:
      loc: 5041.0 12.0 -38.0 0.0 0.0
      type: diamond
      level: 3
      sign: 5041.0 13.0 -38.0 0.0 0.0
    holae:
      loc: 5040.0 12.0 -24.0 0.0 0.0
      type: iron
      level: 0
      sign: 5040.0 13.0 -24.0 0.0 0.0

There are 5 objects in the config, and I tried with debug messages and the code don't arrives to that for()
Why I have this problem, and how can I fix it? Thanks!

 

I don't understand.

 

Looks well, in a couple of minutes I try It.

 

Thanks! Solved.
