Uncaught RangeError: Maximum call stack size exceeded

I start getting this error, the second time I try to update the model with my latest updated data.
…say…agDiagram.model = go.Model.fromJson(agDiagramData);

I used to get this error earlier, that time the reason was that my nodeDataArray had duplicate entries. Currently both my link&nodeDataArrays look good. Also, I don’t have any anonymous function.

Do you have any clue on fixing/debugging this issue?

Without more information, I’m not sure we can help you. Maximum call stack size exceeded suggests that an infinite loop is occuring, for whatever reason.

Is the value of agDiagramData a valid JSON-formatted string?

If it isn’t, I could see that causing problems. For example, if it’s a JavaScript object, its properties and its Arrays (if any) had better follow the requirements of JSON-formatted text – no shared or cyclical references, and only datatypes that JSON knows about: Objects, Arrays, numbers, strings, booleans.

Yes @walter, the value of agDiagramData is always a valid JSON-formatted string. But don’t understand, why this issue is coming up.

Most of the time, the agDiagramData will be same, will that be causing the issue? I mean, even though there is no difference in the current model and the updated model, I am calling “agDiagram.model = go.Model.fromJson(agDiagramData);” always.

My issue got resolved by adding stringify to the JSON again before applying it to the model. i.e., “agDiagram.model = go.Model.fromJson(agDiagramData);”


thanks very much.
