Problems on RemoteObjects Model Replicas

Daes

Hi,
I already post this question on interest list but get no answers.

I have some problems on qt remote objects with models.

First, the second time I require the model, it is already initialized but doesn't work correctly.

Second, the remote access of the model through proxy doesn't seem to work correctly too.

The following code, for example, result in this:

"Standard Remote initialized" : OK
NbRows: 2
Available roles: QVector(0, 2)
First Element: QVariant(QString, "Item1")

"Remote copy already initialized" : KO
NbRows: 0
Available roles: QVector(0, 2)
First Element: QVariant(Invalid)

"RemoteModel through proxy" : KO
NbRows: 2
Available roles: QVector()
First Element: QVariant(Invalid)

Did i missed something?
