MongoDBOutput replaces existing documents, how to $set ?
Hi,
I would like to update documents y my Mongo Collections, the problem is if I use the "update" or "upsert" mode of the component I lose all the existing fields of the document. It actually acts as a "replace" mode.
How can I use the equivalent of the "$set" command so that the existing fields are not losts ?
Thanks,
Maxime
