Help: Grabbing Multiverse World Aliases

Hi,
I'm only on my second plugin development and I'm banging my head on how to do this. One command in my plugin shows a player info on each of the worlds on the server and currently displays the standard names:

• world
• world_nether
• world_the_end
• creative
• etc.

As my server uses Multiverse-Core, I'd like to show the Alias of the world instead.
I tried this to get a list of the world aliases on the server:

Code:java

if (getServer().getPluginManager().getPlugin("Multiverse-Core") != null) {
    getLogger().info("Multiverse Core found!");
    Plugin plugin = getServer().getPluginManager().getPlugin("Multiverse-Core");
    getLogger().info("Get plugin done!");
    // Get a list of worlds that MV apparently has
    WorldManager wm = new WorldManager((MultiverseCore) plugin);
    Collection<MultiverseWorld> wmList = wm.getMVWorlds();                       
    if (wmList != null) {
        getLogger().info("World list is " + wmList.size());
        for (MultiverseWorld w: wmList) {
            getLogger().info("World: " + w.getAlias());
        }
    }
}

The problem is that the list (wmList), while not null is zero length and no Aliases are shown. What am I doing wrong?

 

I found out how to do this by looking at MVInventories:

Code:java

MultiverseCore mvCore;
mvCore = (MultiverseCore) this.getServer().getPluginManager().getPlugin("Multiverse-Core");
Collection<MultiverseWorld> wmList = mvCore.getMVWorldManager().getMVWorlds();
if (wmList != null) {
   getLogger().info("Number of worlds = " + wmList.size());
   for (MultiverseWorld w: wmList) {
     getLogger().info("World: " + w.getAlias());
   }
}
