Hello I get desesperate trying to create a new entry in a Vocabulary using automation (or REST Api). I found the Directory.CreateEntries operations which seems to do exactly what I want.

I prepared a json data file, as described in http://explorer.nuxeo.com/nuxeo/site/distribution/current/viewOperation/Directory.CreateEntries

 {
    "params": {
        "directoryName": "documentationTypes",
        "entries":[{"id":"helptext", "label":"Cool documentation is cool"}]
    },
    "context": {}
 }

And POSTed it to server : http –json POST localhost/nuxeo/site/automation/Directory.CreateEntries < data.json.

But then I get a 500 error message with following log in nuxeo.log

****** chain ******
Name: Directory.CreateEntries
Exception: OperationException

The server is running latest 7.3 ; I'm pretty sure about about the data.json file since the same file used to read entries works perfect. Note that I'm getting same error for other vocabularies or if I try to delete any entry/entries.

Any hint?? What is this about =

No type adapter found for input: class java.util.ArrayList and output class java.lang.String

Many thanks Lisa
