Roger, Can you please try to make a SSCCE (http://sscce.org), zip it up and post to the list. It will enable us to try to help without requiring additional effort just to make the example work, and in many cases merely creating the SSCCE can lead to the identification of the underlying problem.
Just have a minimal BXML file - just a Window, maybe a BoxPane or something and then your ImageView. Have a small class that implements Bindable with the @BXML annotation on the ImageView field, and see if you can replicate the problems you are seeing. If you can replicate the problem, we can investigate it easily. If you can't replicate it, it will give you something to work with to figure out what is wrong in your 'real' code.
