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);

}
}

Kamesh,

Are you using a composed adapter factory that includes the
ResourceItemProviderAdapterFactory?

Hi Ed,

Yes I do have it, am just using those parts for the EMF generated editor

adapterFactory = new ComposedAdapterFactory(
ComposedAdapterFactory.Descriptor.Registry.INSTANCE);

adapterFactory
.addAdapterFactory(new ResourceItemProviderAdapterFactory());
adapterFactory
.addAdapterFactory(new PortalStructureItemProviderAdapterFactory());
adapterFactory
.addAdapterFactory(new ReflectiveItemProviderAdapterFactory());

thats what wonders me .. instead of ViewerPane I am using the sepaerate
EditorPart for the Pages ... the idea behiend is to integrate the Diagram
Editor at later point of time adding flexibility.

Is that has anything to do with IEditorProxy ??? as suggested in the
Integrating EMF-GMF Editor article ??

Regards,
Kamesh

Kamesh,

Given that you're sure an Resource instance is being set as input (when
you say that, do you really mean
org.eclipse.emf.ecore.resource.Resource?) and you've set the content and
label providers with the correct factories, it should just work. My
suspicion would be that the input object isn't what you're assuming.

Hi Ed,

I debugged the issue , the issue was with the ContentOutlineSelection. Its
not able to provide the proper selection element since there was a bug in
the code that I wrote..

I also gave a treeviwer.refresh() after setting the input ..

I have one quick question, how to make the Tree listen to the
ContentOutlineSelection by just navigating to the Selected Element in the
Outline view , I dont need it to go to its children , just stay at the
same element selected by the Outline.

Kamesh,

The generated editor's handleContentOutlineSelection shows how to do
that doesn't it?

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.
