----------------------------------------------------------------
[~jfs],
[~jcamachorodriguez] set me straight on this. It's actually not possible to do
a default value here. My [incorrect] understanding was that "column" mode was a
super-set of "none" mode. Actually, they are a bit different and not really
compatible in this way. The context always needs to be present and the correct
mode needs to be applied.
Possibly the easiest thing is to use {{Preconditions.checkState}} and make sure
the configuration is not 'null'. If it is, an error will be generated during
qtests and you'll get a stack trace showing you where the issues are.
And now there are three modes (none, column, standard), so one can't just have
a single default return value here.
