I am defining a custom filter like so:
<div class="idea item" ng-repeat="item in items" isoatom>
<div class="section comment clearfix" ng-repeat="comment in item.comments | range:1:2">
....
</div>
</div>
As you can see the ng-repeat where the filter is being used is nested within another ng-repeat
The filter is defined like this:
myapp.filter('range', function() {
return function(input, min, max) {
min = parseInt(min); //Make string input int
max = parseInt(max);
for (var i=min; i<max; i++)
input.push(i);
return input;
};
});
I'm getting:
Error: Duplicates in a repeater are not allowed. Repeater: comment in item.comments | range:1:2 ngRepeatAction@https://ajax.googleapis.com/ajax/libs/angularjs/1.1.4/an

The solution is actually described here: http://www.anujgakhar.com/2013/06/15/duplicates-in-a-repeater-are-not-allowed-in-angularjs/
AngularJS does not allow duplicates in a ng-repeat directive. This means if you are trying to do the following, you will get an error.
However, changing the above code slightly to define an index to determine uniqueness as below will get it working again.
