FLARToolKit Camera3D Issues with Away3D 4.1.4 Gold

Question

I've download the latest FLARToolKit build and Away3D 4.1.4 Gold, and it seems that the custom Camera3D support class that comes with FLARToolKit is no longer compatible. I keep getting this error.

Error: An abstract method was called! Either an instance of an abstract class was created, or an abstract method was not overridden by the subclass.
at away3d.cameras.lenses::LensBase/unproject()
at away3d.cameras::Camera3D/unproject()
at away3d.containers::View3D/unproject()
at away3d.core.pick::RaycastPicker/getViewCollision()
at away3d.core.managers::Mouse3DManager/updateCollider()
at away3d.containers::View3D/render()

I've basically just recreated the supplied sample class with FLARToolKit, which has the following line when setting up the Away3D view:

_view.camera = _markerSystem.getAway3DCamera();

Seems the unproject() method needs to be overridden. While doing that and returning a generic vector fixes the issue, it probably makes the method useless! I don't know enough about 3D transforms and matrices to override it properly.

Has anybody encountered this issue? If so, how did you solve it?

I think it is a mouse picking related issue, because the error only occurs when the mouse is over the View. I have disabled mouse picking in the view3d, and the message is gone, but this let the scene out of interactivity:

view3d.mouseEnabled = false;
view3d.mouseChildren = false;
view3d.mousePicker = null;
