Removing elements from arrays

If you load an array it gets treated as an object:

"expansion_prices": {
"0": {
"coins": 501,
"cash": 10
},
"1": {
"coins": 2002,
"cash": 15
},
"2": {
"coins": 3000,
"cash": 20
}, etc

instead of
"expansion_prices": [
[
"coins": 501,
"cash": 10
],
[
"coins": 2002,
"cash": 15
],
[
"coins": 3000,
"cash": 20
], etc.

which causes tons of issues when you are working with sensitive languages such as python for example. Any ideas how to fix this?

OK guys I found a solution. I saw the comment:
//TODO: Deal with array type
in onde.Onde.prototype._sanitizeFieldInfo
and I added a quick workaround. Not pretty at all but works. Inside the function, on the first line add

var stringified = JSON.stringify(valueData);

And where the comment is the following lines:

if ( stringified.charAt(0) == '[' )
{
fieldInfo.type = 'array';
}

And as far as I can see it works fine. I'll do some more testing and I'll let you know if there are any problems.

actually found an issue - cannot use charAt() on an object. So the if condition works as
if ( typeof stringified != 'undefined' && stringified.charAt(0) == '[' )
{
fieldInfo.type = 'array';
}
