Summary Statistics Actor not working
Added by Dan Higgins over 18 years ago.
Updated over 18 years ago.
Description
The Summary Statistic actor is derived from the base RExpression actor. If this
actor is draged to the screen, the ports look right, but if you look at the
parameters, it shows an R script of '2+2' which is the RExpression default
rather than the script in the in the Summary Statistic xml! And if you hook it
up, it just runs the '2+2' rather than the correct script.

This problem looks like it is caused by a failure of the kar parser in the
ActorMetadata class. It looks like this class, which parses the moml in the kar
container simply does not reset actor parameters. (And Chad indicated that he
didn't realize that we needed to do that.)
The problem would apparently occur with any actor that might have parameterized
values (e.g. the R script), with each being saved as a separate distinct version
for the actor list.

The problem was traced to the ActorMetadata class. It runed out that this class
did not reset values of StringAttribute, Parameter, StringParameters (actually
any general Attibute) if the named attribute already existed. This is because a
NameDuplicationException is thrown if one tries to add an Attribute that already
exists.
The fix was to add code to getActorAsNamedObj to handle StringAttribute,
Parameter, StringParameters when they already exist in the container.
