Here's a newbie question. I haven't been able to figure out how to use
CompositeEntity.getEntity() by passing anything other than the simple
name of the entity.
E.g. When I parse the attached workflow and ask for
toplevel.getEntity("Expression6") I get back an entity. But, when I ask
for the entity using the full name of the entity
".parameter-writing-sample-1.Expression6" I get nothing back. Is there
any possibility that "Expression6" won't uniquely name my entity? I
assume that yes there is a possibility and so that's why I'm trying to
use the full name of the entity instead of just the simple name.
