[aerogear-dev] AeroGear.js DataManager Filter Method

[Sebastien Blanc]

Hi,
I'm not really confortable with the double dot, but I have no other idea
for the moment :) (maybe '->' ?).
And should your pseudo code not be written this way :

var filtered = filter({
        "x.sites.'google.com'.type": {
                data:  "search engine"
        }
});

?
Seb
