In many editors, all relevant EReferences may be edited in the diagram
and there is no need for supporting them in the property sheet. The
following code may be inserted in the generated XXXPropertyProvider
and filters out the EReference properties from the EMF section of the
Advanced tab. The shouldRemove method may be changed to change the
filtering strategy. Hope it's useful for others.

protected ICompositePropertySource createPropertySource(Object
object, IItemPropertySource itemPropertySource) {
return new FilteringCompositePropertySource(object,
itemPropertySource, "EMF");
}
private class FilteringCompositePropertySource extends
EMFCompositePropertySource {
public FilteringCompositePropertySource(Object object,
IItemPropertySource itemPropertySource, String string) {
super(object, itemPropertySource, string);
}
protected boolean shouldRemove(IPropertyDescriptor
descriptor) {
if (! (descriptor instanceof
EMFCompositeSourcePropertyDescriptor)) {
return false;
}
EMFCompositeSourcePropertyDescriptor
emfDescriptor = (EMFCompositeSourcePropertyDescriptor)descriptor;
if (emfDescriptor.getFeature() instanceof
EReference) {
return true;
}
return false;
}
public IPropertyDescriptor[] getPropertyDescriptors()
{
IPropertyDescriptor[] descriptors =
super.getPropertyDescriptors();
int count = 0;
for (int i = 0; i < descriptors.length; i++) {
if (! shouldRemove(descriptors[i])) {
count++;
}
}
if (count < descriptors.length) {
IPropertyDescriptor[] descriptors2 =
new IPropertyDescriptor[count];
for (int i = descriptors.length - 1; i
>= 0; i--) {
if (!
shouldRemove(descriptors[i])) {
descriptors2[--count]
= descriptors[i];
}
}
descriptors = descriptors2;
}
return descriptors;
}
}

Ed,
Yes, I'm aware of that, but they are needed in the generated
tree-based editor, which I sometimes have to use, to bootstrap the
models. So, I want them generated, but filter them out, when they're
not needed anymore in (in addition to cluttering the property sheet).

Hi Hallvard,
Instead of removing some properties from the EMF-section I'd rather like
to remove those properties generated in View-section. I know that these
properties are derived from the Node that is displayed, but I don't know
how to prevent my PropertiesView from displaying them.
Could you provide any help in this direction?
I want to remove the view-Properties because I'd like to prevent the
user from editing them. Them user should only be able to change the
layout of the nodes in the graphical diagram-editor with its given
actions (move, resize, etc.).
Thanks for any advice

It's easy with M2, check our project wiki for details.
