Photoshop Scripting with Javascript: How to unlock a partially locked layer?

Question

I've tried many ways to unlock a partially locked layer in Photoshop using Javascript but nothing works. Here's a few examples of what I've tried:

var layerRef = app.activeDocument.artLayers.getByName('Background');
layerRef.allLocked = false;

The below alert returns false:

alert(app.activeDocument.layers[0].allLocked);

So it's not locked? I just want to convert this partially locked layer to a not locked layer.

Background is kind of a particular weird layer type in Photoshop. To unlock it (and convert to a normal layer) you need to use this specific command:

activeDocument.activeLayer.isBackgroundLayer = false;

Using the same property you can check if a layer is a Background layer and you can set any layer as a BG layer.
