ng-repeat throws "Duplicates in a repeater" iterating over an object with identical values

[worrel]

Using

ng-repeat="(key,value) in myObj"

where myObj = {
age: "20",
children: "20"
}

throws "Duplicates in a repeater" error, because the default 'trackByIdFn' is calling hasKey with only the value (not the key). The generated hashes for both myObj.age and myObj.children end up as "string:20", which trips up ng-repeat.

Perhaps trackByIdFn should handle strings/numbers explicitly and use hashKey(key + value) for them? Not sure what else this impacts however.
