Hi Juan,
You need to stop threading before you remove or add views to a
CompositeViewer. i.e.
viewer.stopThreading();
viewer.addView(view);
viewer.startThreading();
The other thing you can do is toggle the cameras associated with the
view off by setting their NodeMask to 0x0/0xffffffff to be off/on
respectively.
