Hi,
I am playing with the Generated EMF editor by removing the inline pages
and creating the Pages as Seperate EditorParts and adding the same to the
Multipage editor.
When my input to the Editor Part is called i see the a XXXResourceImpl is
passed as input
I have added the AdapterFactoryContent and LabelProvider to my tree, when
the editor is opened I am unable to see the Root Element Object or
anything else in the Tree , just an empty tree is visible ..
Can anyone let me know where i would have gone wrong ??
My EditorPart code snippet :
public class TableTreeEditorPart extends AbstractPortalStructureEditPart {
private TreeViewer treeViewer;
private Tree tree;
public TableTreeEditorPart(PortalStructureEditor editor) {
super(editor);
}
/*
* (non-Javadoc)
*
* @see
org.eclipse.ui.part.WorkbenchPart#createPartControl(org.ecli pse.swt.widgets.Composite)
*/
@Override
public void createPartControl(Composite parent) {
treeViewer = new TreeViewer(parent, SWT.NONE);
tree = treeViewer.getTree();
tree.setLayout(new FillLayout());
tree.setLinesVisible(true);
tree.setHeaderVisible(true);
treeViewer.setContentProvider(new AdapterFactoryContentProvider(
getAdapterFactory()));
treeViewer.setLabelProvider(new AdapterFactoryLabelProvider(
getAdapterFactory()));
createContextMenuFor(treeViewer);
getEditorSite().setSelectionProvider(treeViewer);
}
/*
* (non-Javadoc)
*
* @see org.eclipse.ui.part.WorkbenchPart#setFocus()
*/
@Override
public void setFocus() {
tree.setFocus();
}
/*
* (non-Javadoc)
*
* @see
com.accenture.portal.tools.xasgen.portalstructure.presentati on.parts.AbstractPortalStructureEditPart#setInput(java.lang. Object)
*/
@Override
public void setInput(Object input) {
System.out.println("TableTreeEditorPart.setInput() : " + input);
assert input != null;
assert treeViewer != null;
treeViewer.setInput(input);
}
}

Thanks Ed. I am able to rectify it .. Also i do have a one more question on
the Selection ,
I am using the MultipageSelectionProvider for the Editor , in my tree when i
click on the node and add a child or sibling my Selection still remains on
the Node from which I initiated the Command , my question is how do I move
the selection to the newly added element ???
This works fine with the Generated editor , my doubt is that am making a
mess with the Selection with my dissected EMF editor ???
Thoughts please ...

Kamesh,
The generated editor's setCurrentView method handles updating the
selection and listening to the current view to forward its selection.
So I guess you need to hook up your MultipageSelectionProvider thing so
that it serves the same kind of purpose...

Ed,
Thanks for your toughts ! The reason it was not working is that 1. As =
you said the currentViewer was not set and there by when the commands =
are fired the setSelectionToViewer method was not able to perform its =
task of setting the selection to recentlyAffectedObjects .
So I tried to set the CurrentViewer on pageChange where each page of my =
multipage editor part is associated with an StructuredViewer.
