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;

While Mr. Saqoosha implements a 4.1.4 Gold version of the FLARToolkit
