I see that the Database Joiner transformer only supports the Open API for file geodatabase, it would be useful if it suppported ArcObjects as well.
To flesh this out a little more, basically allowing the same functionality as the ArcObjects reader when bringing in a file gdb table in this tranasformer would be useful. Of coruse the workaround is to add a reader and feature merger, but the functionality in the single transformer would be useful.
