How to create a new layer at the top of the stack, add objects to it, and lock it.

gistfile1.js

	var dom = fw.getDocumentDOM(),
		currentLayerIndex = dom.currentLayerNum,
		newLayerIndex;
		
	dom.addNewLayer(null, false);
	
		// currentLayerNum is set to the newly added layer
	newLayerIndex = dom.currentLayerNum;
	
		// put the new layer before the last layer.  note that this won't work
		// if the Web layer has sublayers.
	dom.reorderLayer(newLayerIndex, dom.layers.length - 1, 0, 1);
	
		// add an object to the new layer and lock it
	dom.addNewRectangle({ left: 0, top: 0, right: 100, bottom: 100 }, 0);
	dom.setLayerLocked(-1, -1, true, false);
	
		// focus the previously active layer
	dom.currentLayerNum = currentLayerIndex;
