In perspective i have following script: you see the data as a string will be succesfull parsed to a dataset. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/0/07ec00f674ee124bc085269632b6febe31c014c8.png) But with a long/integer it wouldnt do that ☹ ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/9/900d3df4df056eaf3adca39d573958a5c1f7c447.png) It gives a java.lang.ClassCastException ---

The `data` parameter is supposed to be a _list_ of rows (list of lists), which is why it works when you append `[3]` and not `3`.
