DelegatingWrapperItemProvider : how change the order of the properties [message #1412538]

Hello

i work on a editor (which extend EcoreEditor).
I need to display in a certain order the properties of the selected object (of the tree editor.)
This order should be computed with some information (eAnnotations) which are stored in the ecore model.
Unfortunatly, i cannot get the descriptor from the PropertySheetEntry. Do you know how could i get it ?

The other alternative would be to directly get the DynamicEObjectImpl but the selected object is a org.eclipse.emf.edit.provider.DelegatingWrapperItemProvider
and i do not know how to get the corresponding DynamicEObjectImpl. Do you know how to solve that problem ?
thank you in advance

Philippe

So I assume you're doing this for a dynamic model and you're using the
reflective editor... It would generally seem the easiest to hook into
org.eclipse.emf.edit.ui.provider.AdapterFactoryContentProvider.createPropertySource(Object,
IItemPropertySource) because then you have control over what's returned
by
org.eclipse.emf.edit.ui.provider.PropertySource.getPropertyDescriptors(). Given
you're extending an existing editor, it's a little trickier to get your
specialized content provider in place. You'd need to specialize
org.eclipse.emf.ecore.presentation.EcoreEditor.getPropertySheetPage() to
make sure your specialized content provider is used.

Thanks Ed,
Yes, you are right, i am working with a dynamic model and using the reflective editor.
From my specialized PropertySource.getPropertyDescriptors(), to be able to change the order of IPropertyDescriptor[],
i need to read the eAnnotations (having the order information) of the DynamicEObjectImpl. However, the objects are of type DelegatingWrapperItemProvider and not DynamicEObjectImpl.
And i do not know how to access this information ?

You can always unwrap things:
org.eclipse.emf.edit.domain.AdapterFactoryEditingDomain.unwrap(Object)
