This implied coding error is appearing infrequently in the Java Console session:

I have forwarded this information to engineering as they continue to investigate this issue.

When you create a new portfolio and do not populate it immediately with any stocks, you get the following code error from Java upon refresh to add the portfolio to the drop-down list:

Note....I'm exploring the spin-off problems associated with the error, as this simple bug may lead to leak and the 100% CPU. It's also too easy to create, i.e. adding portfolio is an obvious first step with LC2.
