Cannot override PrintQuote on QuoteMaint

        public delegate IEnumerable PrintQuoteDelegate(PXAdapter adapter);

        [PXOverride]
        public IEnumerable PrintQuote(PXAdapter adapter, PrintQuoteDelegate baseMethod)
        {
                IEnumerable returnValue = adapter.Get();

                try
                {
                    returnValue = baseMethod(adapter);
                }
                catch (PXReportRequiredException ex)
                {
                    ex.Mode = PXBaseRedirectException.WindowMode.New;

                    throw ex;
                }

                return returnValue;
        }

Any ideas?  Customer wants this to re-direct to a tab instead of same window
