            Reporter: paul iannazzo


##file helpers.js in views/lib/common
const _ = require("views/lib/underscore");
Array.prototype.compact = function(){return _.compact(this);};
Array.prototype.flatten = function(){return _.flatten(this);};

//this function is called from views.someName.map
function commonProperties(doc){
    arr = [];
    arr = arr.compact();
    log(arr);
    log("is array?");

the .compact() lines that are commented out cause errors:
[info] [<0.3429.0>] OS Process #Port<0.5316> Log :: []
[info] [<0.3429.0>] OS Process #Port<0.5316> Log :: is array?

(new TypeError("doc.store.taxes.compact is not a function", "", 29)) with doc._id RT7-RT7-31-20

the first logs show that doc.store.taxes is an array, why do i need to use Array() on it in
order to use the prototype functions?
