Yes, but this seems like a problem with Treemap. The Treemap should realize that each row represents a different node (that's how the data is specified). It should "unique-ify" the data on its own, perhaps by internally combining the row number with the value.
However Treemap does this, it's part of implementing a Treemap and shouldn't be something that each user of the Treemap would have to reinvent on his/her own FormattedValue is just a workaround for this problem. Not a pretty one, either, as it involves first junking up your Treemap datasource, and then trying to clean it up with formatters...
