Cannot read property className of null #8

Hi Eric,

I've been having issues with your widget, whereas I keep getting the following error Cannot read property 'className' of null TypeError: Cannot read property 'className' of null at Object.add (http://localhost:8080/mxclientsystem/mxui/mxui.js?637123462599532212:5:100797) at _handleResults (http://localhost:8080/widgets/CellStyler/widget/CellStyler.js?637123462599532212:1:3099) at http://localhost:8080/widgets/CellStyler/widget/CellStyler.js?637123462599532212:1:1961 at O (http://localhost:8080/mxclientsystem/mxui/mxui.js?637123462599532212:79:25829) at http://localhost:8080/mxclientsystem/mxui/mxui.js?637123462599532212:20:25601

My setup is pretty simple, the column Naam is also visible in the datagrid. I've also tried placing the widget above and below the datagrid. I've also tried using a nanoflow or the built in JavaScript option. Neither work.

Hope you can help!

Modeler version is 7.23.4

After some more testing, I came to find that the error occurs when I enter a Column name in the Rules section. When I leave this empty, the class is applied.

However, I want to style only the specific cell when the rule = true, not the entire row or the entire column.

Seems I was conflicted by the documentation, where it showed me I had to use the name of the attribute in the column as the 'columnName' property. But I actually needed to entery the columnName as the property of the datagrid widget (so column4 in my case). Now my class is applied correct
