i assigned new Model() to the field.
String sym = (String) new Model().getObject();
int stockValue = sym.hashCode() % 100;
QuoteResult quoteResult = new QuoteResult(stockValue);
setResponsePage(quoteResult);
and it still threw the same error.
i also found some additional inform from clicking the display page view.
Page
[Page class = myapp.stockquote.GetQuoteSymbol, id = 0, version = 0]:
