Hi all,
I wanted to use the ControlDecoration class to visualize the validation
status of a Binding on the corresponding UI control. In order to retrieve
the decoration images predefined in JFace, I'm using the following code
FieldDecorationRegistry.getDefault().getFieldDecoration(
FieldDecorationRegistry.DEC_ERROR).getImage();
However, this always results in the below exception being thrown as the
images seem not to be found. I guess it's once more some CLASSPATH/ClassLoader
problem but I cannot figure out what I have to do to be able to use those
images from within the data binding snippets (without having to hardcode
the images' path).
Any suggenstions? Thanks in advance!
Regards,
Ovidio
The image could not be loaded: FileImageDescriptor(location=class
org.eclipse.jface.fieldassist.FieldDecorationRegistry, name=images/error_ovr.gif)

Hi again,
it seems as if it was some bug. I was having that problem with Eclipse
Ganymed M6 but with the RC1 version which I have just downloaded, the
exception is gone.

Yes there was a change in how ImageDescriptors work and there was a bug
introduced some time in the dev-cycle.
