Hi,

I encounter a problem while I'm been trying to display a TreeViewer,
this one is not displayed.

Here is the creation code inside a Dialog :

 private void createContents(final Shell shell) {
       MetaModel metamodel =
MetaModelRegistry.getInstance().getMetaModel();
       WidgetBuilder wb =
WidgetBuilderFactory.createWidgetBuilder(metamodel, new
CorporateDesignImpl());
       MdfRegistry reg = MdfRegistry.getInstance();
       TreeViewer treeViewer = new TreeViewer(shell,SWT.MULTI |
SWT.H_SCROLL | SWT.V_SCROLL);
       treeViewer.setContentProvider(new MDFTreeElementContentProvider
());
       treeViewer.setLabelProvider(new MDFTreeElementLabelProvider());
       treeViewer.setInput(reg);
   }

Thanks for your help.

Regards,

Alexandre
