Hi Bill,
The problem was that we'd never had a transformer that could create
more than one list, and had no mechanism for handling that.
The NeighborFinder was the first to hit that snag. The lists get
created but don't get visualized within Workbench. You can just add
the name using the AttributeExposer and all should be well.
EG if you enter 1stStreets{}.AnAttributeName in the AttributeExposer
then that list attribute will be exposed - you then need to right
click it (as with any list) and choose to expose elements within the
list or just handle them with transformers.
I'm told the problem is fixed with FME2008, which is capable of
handling any number of lists in a single transformer.
Hope this helps,
Mark

there a difference between the objects in the Candidate List vs the

streetnames in a destination attribute called StreetList
