Your contextObj has no attribute with the name ‘New’, therefor it finds no object and thus cannot read properties. Change it to
Or with trial and error attempt to do this first with the most simpel statement: “return true;”, should turn your cell into background-danger. Then “ return rowObj.get("OrderStatus")==’<yourcellcontents>’, see what happens. And so on.
Solved the Problem with
return rowObj.get("OrderStatus") == "_New";
The underline was missing.
Thanks for you Help
