ListGrid startEditingNew getCellCSSText conflict

[msteninger]

I have a ListGrid with a modified getCellCSSText function, to change some rows to a red highlight based on certain criteria. AutoFetchData is false.

Here's the function

            getCellCSSText: function (record, rowNum, colNum) {
                if (record.INVENTORY_ITEM_ID == "") {
                    return "font-color : red;";
                } else {
                    return "font-color : black;";
                }
            }

However, when startEditingNew() is called to add a new row, before it even draws the blank row to enter data, I get the following error, and the blank row is never presented:

record has no properties
if (record.INVENTORY_ITEM_ID ==""){

After that, the listGrid refetches its data.

How I can tell the listGrid not to call getCellCSSText when startEditingNew is called?

You can't, but you can trap this pretty easily by returning null if record is null...
