ImageRegistry problem [message #636928]

Hello,
I have code using ImageRegistry that works in RAP 1.3 but not 1.4.0 M2.
ImageRegistry.get(key) now always returns the latest image put in the
registry, but not the one associated with the key.
Is it a known bug?
Thanks,
Patrick

Hi Patrick,
sounds like a bug for me. Could you provide a snippet that demonstrate the problem?
Thanks,
Ivan

Sure, here it is:

public void createPartControl(Composite parent) {
ImageRegistry imageRegistry = Activator.getDefault().getImageRegistry();
URL url = Activator.getDefault().getBundle().getEntry("/icons/1.gif");
imageRegistry.put("1", ImageDescriptor.createFromURL(url).createImage());
url = Activator.getDefault().getBundle().getEntry("/icons/2.gif");
imageRegistry.put("2", ImageDescriptor.createFromURL(url).createImage());
Label image = new Label(parent, SWT.NONE);
image.setImage(imageRegistry.get("1")); // displays image 2 :(
}

Hi Patrick,
your snippet works fine for me against CVS HEAD. Maybe you run into this bug:
326888: InternalImageFactory uses same HashCode for different images
https://bugs.eclipse.org/bugs/show_bug.cgi?id=326888
which has been fixed in CVS HEAD and will be available in 1.4M3.
Could you provide the two images used in the snippet to double check it?
Best,
Ivan

You are right, this must be this bug, because my images only differ by
their color. I'll wait for 1.4M3. Thanks for the help.
