Circular Reference in grid object

[minalkumar2893]

I found a circular reference in the grid object. You can check out this video to understand better. I used the example posted in the ui-grid homepage to reproduce the issue.

Please revert if this is an actual bug.

Circular references are quite normal. Even AngularJS uses them in the scope object. You should not have a problem with them.

The only problem with them is when you want to copy an object with a circular reference in it. JSON.stringify() throws. angular.copy() may throw (since it keeps a ref index). Any deep merger will probably throw.

You can filter out the references if you want, by using JSON.stringify's replacer (second) argument: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Cyclic_object_value

You can also look at above link, in the "see also" section re a JSON parser/stringifier and their solution, using a {$ref} object.
