attachment can not be null

[rkimaoui]

Hello,

When i save Message class without setting file, i get this error:

 [elasticsearch[Dominic Petros][transport_client_worker][T#5]{New I/O worker #5}] ERROR grails.plugins.elasticsearch.index.IndexRequestQueue - Failed bulk item: MapperParsingException[No content is provided.]

file nullable: true doesn't seem to work.

Here is my code:

class Message {
String text
String file

    static transients = ['file']

static searchable = {
        only = [ "file", "text" ]
        file attachment: true
    }

def setEncodedData(String str){
        file=str
    }

static mapping = {
        id column: "ID_MSG", generator: "identity"
        version false
           text type: 'text'
    }

static constraints = {
        file nullable: true
    }
}

Thx in advance !

Which version of Grails and plugin are you using? Also, it would be great if you could create sample grails application describing the problem over GitHub.
