List property is an empty object in Component.onCompleted [solved]

[manuelsch]

Hi,

I have defined a new Component in the file "MongoDB.qml"
@import Qt 4.7
import "MongoDB.js" as MongoDB
import "../json/json2.js" as Json

Item {
id: mongoDatabase

property string name
property string host: "localhost"

property list<MongoCollection> collections

function stats() { return MongoDB.db.stats() }

Component.onCompleted: {
    MongoDB.init(Mongo.init(host), name)

    console.log(Json.JSON.stringify(mongoDatabase.collections))
    console.log(mongoDatabase.collections)
}

}
@
And then I use this MongoDB component in my main QML file like this:
@
import "QtMongo"

[...]
ListView {
id: listview

        MongoDB {
            id: db
            name: "testdb"
            host: "localhost"

            collections: [
                MongoCollection {
                        id: mythings
                        name: "things"
                }
            ]
        }

[...]
@
The problem is, that in MongoDB's Component.onCompleted the variable mongoDatabase.collections is always an empty object ("{}").
Can anybody tell me why? From my point of view, it should be an array including a MongoCollection called mythings.

Edit: the MongoDB.qml and MongoCollection.qml files are in the same directory (called "QtMongo") and my main QML file is in the parent directory.

ahh, ok, I made it work:
You cannot use a for-in-loop. Only for(i =0; i<collections.length;++i)-loop
