Trader does not handle NULL from Broker
Closed this issue · 1 comments
CC9759 commented
When the DB is inaccessible/missing/misnamed, Broker takes in a null value and Trader does not check. As a result Trader errors out and the website redirects to the error message:
Error 500: java.lang.NullPointerException: Cannot read the array length because "<local6>" is null
rather than a more user-friendly view.
The source of the problem should be from summary.jsp where broker is called. It returns a NULL value that isn't checked and will error out the program.
Trader's Log:

Fixed this a long time ago (I believe by merging a PR that Celina submitted). Just forgot to close out this issue at that time.
