> https://bugs.adobe.com/jira/browse/SDK-9801
> Steps to reproduce:

> Sorting should work, no RTE.
>
> Workaround (if any):
> None
> It seems like the same logic that was implemented in data grid and data grid
> column needs to be implemented in Sort.as. The logic seems to get hung up in
> the Sort.findItem method:
> var hasFieldName:Boolean;
> try
> {
> hasFieldName = values[fieldName] !== undefined;
> }
> catch(e:Error)
> {
> hasFieldName = false;
> }
> this code won't handle complex values.
