Data structure suggestion

[gmarco]

Hi, In my little addons I used a files categories.lua where the users define the custom mounts or pets to be summoned.

The structure is very simple:

mounts = { 
   
   flying = {
        "Draco Del Crepuscolo",
        "Draco Rosso",
        "Fenice Oscura",
        "Proto-Draco Ferroso",
   },
   
   ground = {
        "Fiera della Luna Rapida",
        "Fiera della Nebbia Rapida",
        "Fiera della Notte Striata",
 
     },
   
[etc etc ...]
 
}

Now I'd like to try to move and replicate this data structure into the addons to use the WTF store method. But what I think was easy is not so easy.

Let's suppose I wanna add a mount in a category not yet defined with the syntax:

/mrc add new_category Swift Moonsaber

The parsing should be ok and suppose I have:

mounts = {}
category="new_category"
mount="Swift Moonsaber"

I thought that it could be simple as push a new entry in this way:

mounts[category][mount]=true

but here lua complain something about attempt to index field '?' (a nil value).

I try also with table.insert without any fortune.

I don't think things change so much removing one level ( categories[mount]=true ) being this to be pushed inside the mounts{} to be saved later.

Thanks in advance for your patience.
