> After pressing sort on a column, I'm getting the exception below:
> The method with the NPE is:
> public List<Object> wrapList(List<Object> list) {
> ELContext elContext = context.getELContext();
> VariableMapper mapper = elContext.getVariableMapper();
> varValue = mapper.resolveVariable(var);
>
> convertList(list, new ObjectConvertor() {
> public Object convert(Object o) {
> return wrapObject(o);
> }
> });
>
> return list;
> }
> I debugged the code and found out, that mapper is null after the line
> VariableMapper mapper = elContext.getVariableMapper();
> elContext implementation type is org.apache.myfaces.el.unified.FacesELContext
