[Polyglot]

What steps will reproduce the problem?

1. Downloaded josm-latest.jar and had the same problem as reported in https://josm.openstreetmap.de/ticket/13293
2. opened PT.osm
3. ran validation (full), aborted, then ran validation by using the upload button, so only modified objects will be validated.

What is the expected result?

What happens instead?

The error was because the platforms in the new code were treated as Nodes, whereas they can be Ways too. The fixed version only performs that test if the platform is a Node.

Please update to revision 32791.
