Hello,
i have a problem with the ImageDescriptor
If i'm loading a image via the ImageDescriptorImage, the Descriptor
method createImage throws a NullPointerException.
It seems that the images are missing in the binary build but I added
the image folder to the build.properties.
Have i overlooked anything in the configuration?
thanks for your help.
- Markus
