ClassCastException: org.bson.LazyBSONList cannot be cast to org.bson.types.BasicBSONList about ff4j HOT 5 CLOSED

Hum... is it a trick from the mongodb-driver returning different BSONList if the list is empty ? I'm pretty sure to test this behaviour if roles are set.

Well I would like to cast to the common upper class "BSONObject" but it's not iterable.... I will have to use the ugly (instanceof ?) beurk...

from ff4j.

Well, cannot reproduce this one (Mongodb v2.6.3, MongoDriver v2.12.2)

db.feature.find({"_id":"AwesomeFeature"}).pretty();

{
    "_id" : "AwesomeFeature",
    "enable" : true,
    "description" : "some desc",
    "groupname" : null,
    "strategy" : null,
    "expression" : null,
    "roles" : [ ]
}

Test passing (no exception at least)

// Given
 MongoCredential credential = MongoCredential.createMongoCRCredential("xx", "yyy", "xxx".toCharArray());
ServerAddress adr = new ServerAddress("localhost", 22012);
MongoClient mongoClient = new MongoClient(adr, Arrays.asList(credential));
DBCollection features = mongoClient.getDB( "FF4J" ).getCollection("feature");
// When
FeatureStore mongoStore = new FeatureStoreMongoDB(features, "ff4j.xml");
Feature f = mongoStore.read("AwesomeFeature");

still investigate...

Hum... I'm using the same versions

I made a little patch for my purpose and I just check the existence of the field in mapAuthorization method (FeatureDBObjectMapper.java)

        if (dbObject.containsField(ROLES)) {
            for (Object role : (Iterable) dbObject.get(ROLES)) {
                authorisation.add(role.toString());
            }
        }

Could you check with a null value instead of an empty value ?

(I'm sorry, I'm not on this bug right now, I'll try again and I'll give you more informations)

I also test with the null value and same result. The test for existence was already there but casting as Iterable is a good enough solution work in all cases. I will go this way.

Corrected in 1.3.1 with the iterable trick
