Subject Re: maven-cvt: console regressions
Date Mon, 25 Sep 2017 12:15:36 GMT
Hi Dale,

Argh! … ok that seemed to be so obviously wrong that my brain didn’t even seem to remember
“fixing” that.
Maybe I shouldn’t delegate fixing things to my co-processor ;-)

But it does show that it might be good to start doing, what I had introduced for the Flex
project. As soon as we merge things back, I think it would be a good idea to start run something
that utilizes the entire stack and verified via Selenium that the console output is as desired.

    The problem was introduced here: https://github.com/apache/incubator-edgent/pull/309/commits/78a3e6fdc935993a5c0445e16e732ae25bbc6b52
    obj.opId was set correctly on line 52 (from op.opId).  After the change the value (now
from met.opId) I believe ended up being null which subsequently messed up other processing.
 Why the original no-op assignment was there… who knows?  :-)
