Right. My response applies more to David's issue.

The state of features read from your web service is null, isn't it? Do
you really need it to be "unknown"?

As I said in another post features drawn with the draw feature control
get the INSERT state automatically.

If you still want to set the UNKNOWN state yourself you can do:

vectorLayer.events.on({
    "featureadded": function(o) {
        var feature = o.feature;
        if (feature.state != OpenLayers.State.INSERT) {
            feature.state = OpenLayers.State.UNKNOWN;
        }
    }
});
