Data
    var/list/Cache
    
    proc/Add2Cache(text)

        if(!Cache)
            Cache=list()

        if(!Cache["Test"])
            Cache.Add("Test")

        Cache["Test"] += text

var/Data/Data = new    

mob/verb
    Cache_Add(t as text)
        Data.Add2Cache(t)


Now this is obviously not the same context I'm using, but it is fundamentally the same. Why can't I check the contents of Data.Cache["Test"] with something like:
mob/verb
    CheckData()
        for(var/a in Data.Cache["Test"])
            world<<a

I believe Cache["Test"] points to a string in this case.

I'm assuming by how you want to access the data, you intend Cache["Test"] to point to a list?


You can verify this with:

world << Cache["Test"]


if you want to add individual strings to a list, you'd have to initialize Cache["Test"] as a list, like:

        if(!Cache["Test"])
            Cache.Add("Test")
            Cache["Test"] = list()

By the way, you can set associations without adding the key first.
var data[0]
data["key"] = value

But in your case, you need to make sure Cache["Test"] is actually a list. What you did is add to null (which is the initial associated value) just like if you added to an uninitialized list variable.

Oh, alright. Haha, silly me. I knew it was something simple! anyways, thanks guys. Now the real challenge is finding out which one of you two deserves the up vote. xD
