(YHOO) is now trading under the name Altaba > Inc. (AABA) and therefore the stock ticker does not return any valid > information anymore. The response from the Yahoo Finance API looks like this: > {code} > "IBM",153.32,2953715,"1:07pm" > "GOOG",963.36,595534,"1:07pm" > "AAPL",149.6144,10235115,"1:07pm" > "YHOO",N/A,0,N/A > {code} > The application crashes because the StockTickInput operator can't parse "N/A" > as a valid double. Changing all the ticker symbols from YHOO to AABA should > fix this. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
