Possible bugs within RoiListener and Roi

Dear all,

I have a plugin where I want to associate a RoiListener to two given ImagePlus within a plugin (having at least 4 ImagePlus).
In the case I write .addRoiListener(this); to the 2 ImagePlus I want to listen, I get then always 2 "detections" within the public void roiModified method.
As if I associate the .addRoiListener(this); to only one picture, I get then 1 "detection" within the public void roiModified method and this on both pictures (i.e. even the one on which I didn't add a RoiListener).
So is this behavior expected and thus am I doing something wrong or is it a bug?

Besides this let's say a user defines a rectangular ROI within one of these 2 ImagePlus and then clicks next to the already created ROI which then deletes the previously defined Roi.
I would then expect that if you use the method .getRoi() on this ImagePlus, the result will be null, but in fact the method returns a Roi which (when using the method .getBounds()) has the same origin than the previous one but a width and height equal to 0.
Is this as well expected or a bug?

I thank you very much for your lighting on this.

My best regards,

Philippe
