Buggy source:

Fixed version (ground truth):

  String color=null;

  if (rec != null && (rawData=rec.getRawData()) != null) {
    color=getStyleAttributeForListItem(listItem,isSelected,ISupportRowStyling.ATTRIBUTE.BGCOLOR,asInlineCssString);
    if (rowBGColorProvider != null) {
      Object c=color;
      String type=null;
      String cellName=null;
      if (rawData.containsCalculation(rowBGColorProvider)) {
        Record.VALIDATE_CALCS.set(Boolean.FALSE);
        try {
          c=rec.getParentFoundSet().getCalculationValue(rec,rowBGColorProvider,Utils.arrayMerge(new Object[]{new Integer(listItem.getIndex()),new Boolean(isSelected),type,cellName,Boolean.FALSE},Utils.parseJSExpressions(getRowBGColorArgs())),null);
        }
  finally {
          Record.VALIDATE_CALCS.set(null);
        }
      }
 else {
        try {

        }
 catch (        Exception ex) {
