I want to to fulfill this fuction: In EditorA, I create a view with an
element called "data", when I double click this View, it will create a new
Editor EditorB, and create another view with the same element "data" In
EditorB.But it seems like that the view in EditorB does not listen to the
change of its element "data".
The code is listed below:
first, I installed the editorPolicy in NodeEditPart:
installEditPolicy(EditPolicyRoles.OPEN_ROLE, new OpenEditorEditPolicy());
Second, I overwrite the getOpenCommand() method of OpenEditorEditPolicy:
protected Command getOpenCommand(Request request) {
//Use ProcessDiagramEditorUtil to create a new Editor EditorB and it will be
ActiveEditor.
ProcessDiagramEditorUtil.createAndOpenDiagram(
ProcessDiagramFileCreator.getInstance(),
(new Path("testActionByProcess"))
.makeAbsolute(),
"dzh.diagram", EditorUtil
.getInitialContents(), "Process",
window, subProgressMonitor, true, true);
IWorkbenchWindow window = ProcessDiagramEditorPlugin.getInstance()
.getWorkbench().getActiveWorkbenchWindow();
//get EditorB
FileDiagramEditor targetDiagramEditor = (FileDiagramEditor) window
.getActivePage().getActiveEditor();
CreateViewRequest.ViewDescriptor viewDescriptor = new
CreateViewRequest.ViewDescriptor(new EObjectAdapter(data), Node.class, null,
ProcessDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT); //the element data is
the element I had just created in EditorA
CreateViewRequest cvRequest = new CreateViewRequest((viewDescriptor));
Command cmd =
targetDiagramEditor.getDiagramEditPart().getCommand(cvReques t);
return cmd;
}
By doing so ,I can create different view in two Editor with the same element
..
The problem is that,in EditorA, when I change the name of element "data" in
its property view ,the view changes immediately, but in EditorB, when I
change the name of element "data" in its property view, the view didn't
change at all, unless I refresh the EditorB manually.
It seems like that the view in EditorB does not listen to the change of its
element "data".
It must be something wrong. And I was hold up by this for quite a few days,
looking forward to your answers.
By the way, does I set the parameter 'new EObjectAdater(selectedElement)'
right, or it should be something else?
I had follow the suggestion of this news listed below.

I found that if I create Shortcut programmatically in the same editor, it
works fine:) The code below :
protected Command getOpenCommand(Request request) {
//Use the same Editor
targetDiagramEditor=(FileDiagramEditor)window.getActivePage( ).getActiveEditor();
DiagramImpl
targetdiagramImpl=(DiagramImpl)targetDiagramEditor.getDiagra mEditPart().getModel();
TransactionalEditingDomain
editingDomain=targetDiagramEditor.getEditingDomain();
CreateViewRequest.ViewDescriptor viewDescriptor = new
CreateViewRequest.ViewDescriptor(
new EObjectAdapter(eclEntityImpl), Node.class, null,
ProcessDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
CreateCommand command = new CreateCommand(editingDomain, viewDescriptor,
targetdiagramImpl) {
protected CommandResult doExecuteWithResult(
IProgressMonitor monitor, IAdaptable info)
throws ExecutionException {
CommandResult result = super.doExecuteWithResult(monitor, info);
View view = (View) ((IAdaptable) result.getReturnValue())
.getAdapter(View.class);
if (view != null && view.getEAnnotation("Shortcut") == null) {
//$NON-NLS-1$
EAnnotation shortcutAnnotation = EcoreFactory.eINSTANCE
.createEAnnotation();
shortcutAnnotation.setSource("Shortcut"); //$NON-NLS-1$
shortcutAnnotation.getDetails().put(
"modelID", ProcessDiagramEditPart.MODEL_ID); //$NON-NLS-1$
view.getEAnnotations().add(shortcutAnnotation);
}
return result;
}
};
try {
OperationHistoryFactory.getOperationHistory().execute(comman d,
new NullProgressMonitor(), null);
} catch (ExecutionException e) {
ProcessDiagramEditorPlugin.getInstance().logError(
"Unable to create shortcut", e); //$NON-NLS-1$
}
}
But if I create Shortcut programmatically in different editors, it come out
the problem, the view does not listen to the change of the element. The code
below:
protected Command getOpenCommand(Request request) {
//create new Editor
IProgressMonitor progressMonitor = new NullProgressMonitor();
progressMonitor.beginTask("Creating diagram and model files", 4);
//$NON-NLS-1$
final IProgressMonitor subProgressMonitor = new SubProgressMonitor(
progressMonitor, 1);
ProcessDiagramEditorUtil.createAndOpenDiagram(
ProcessDiagramFileCreator.getInstance(), (new
Path("testActionByProcess")).makeAbsolute(), "dzhprocess_process.diagram",
EditorUtil.getInitialContents(), "Process", window,
subProgressMonitor,
true, true);
targetDiagramEditor=(FileDiagramEditor)window.getActivePage( ).getActiveEditor();
DiagramImpl
targetdiagramImpl=(DiagramImpl)targetDiagramEditor.getDiagra mEditPart().getModel();
TransactionalEditingDomain
editingDomain=targetDiagramEditor.getEditingDomain();
CreateViewRequest.ViewDescriptor viewDescriptor = new
CreateViewRequest.ViewDescriptor(
new EObjectAdapter(eclEntityImpl), Node.class, null,
ProcessDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
CreateCommand command = new CreateCommand(editingDomain, viewDescriptor,
targetdiagramImpl) {
protected CommandResult doExecuteWithResult(
IProgressMonitor monitor, IAdaptable info)
throws ExecutionException {
CommandResult result = super.doExecuteWithResult(monitor, info);
View view = (View) ((IAdaptable) result.getReturnValue())
.getAdapter(View.class);
if (view != null && view.getEAnnotation("Shortcut") == null) {
//$NON-NLS-1$
EAnnotation shortcutAnnotation = EcoreFactory.eINSTANCE
.createEAnnotation();
shortcutAnnotation.setSource("Shortcut"); //$NON-NLS-1$
shortcutAnnotation.getDetails().put(
"modelID", ProcessDiagramEditPart.MODEL_ID); //$NON-NLS-1$
view.getEAnnotations().add(shortcutAnnotation);
}
return result;
}
};
try {
OperationHistoryFactory.getOperationHistory().execute(comman d,
new NullProgressMonitor(), null);
} catch (ExecutionException e) {
ProcessDiagramEditorPlugin.getInstance().logError(
"Unable to create shortcut", e); //$NON-NLS-1$
}
}
so I think i t must be "they are not using the same ResoureSet by both
diagrams" refers to Alex mentioned in
http://dev.eclipse.org/newslists/news.eclipse.technology.gmf /msg04116.html ,
am I right?

yes , I notice that, and in second situation - using shortcut in different
editor, I set the shortcut in DiagramB with the element which I just
created in DiagramA.
Sorry for not explaining clearly in my previous news.
CreateViewRequest.ViewDescriptor viewDescriptor = new
CreateViewRequest.ViewDescriptor( new EObjectAdapter(actImpl ), Node.class,
null,
//the actImpl is the element I just created in default.process_diagram, I
want to creat the shortcut using the element from DiagramA
ProcessDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
If I select element on DiagramA and change something in a properties view
for this element , the shortcut( I create it programmatically using the
element in DiagramA) in DiagramB does not listen to the change, unless I
refresh it manually( I have to double click on the shortcut's name and it
will reflect the change of element in DiagramA).
If I select shortcut on DiagramB and change something in a properties view
for this shortcut , the element in DiagramA is updated immediately without
needing to update it manually, but the shortcut I selected in DiagramB does
not listen to the change in the properties view.
But if I create the shortcut using the element I just created in the same
editor, it works perfectly, either change something in a properties view
for this shortcut or in a properties view for the element, both the shortcut
and the element update immediately.
I don't know why?
the complete code:
protected Command getOpenCommand(Request request) {
//create new Editor
IProgressMonitor progressMonitor = new NullProgressMonitor();
progressMonitor.beginTask("Creating diagram and model files", 4);
final IProgressMonitor subProgressMonitor = new SubProgressMonitor(
progressMonitor, 1);
ProcessDiagramEditorUtil.createAndOpenDiagram(
ProcessDiagramFileCreator.getInstance(), (new
Path("testActionByProcess")).makeAbsolute(), "dzhprocess_process.diagram",
EditorUtil.getInitialContents(), "Process", window,
subProgressMonitor,
true, true);
targetDiagramEditor=(FileDiagramEditor)window.getActivePage( ).getActiveEditor();
DiagramImpl
targetdiagramImpl=(DiagramImpl)targetDiagramEditor.getDiagra mEditPart().getModel();
TransactionalEditingDomain
editingDomain=targetDiagramEditor.getEditingDomain();
ActivityImpl actImpl = ... ; //get the ActivityImpl is the element I just
created in DiagramA
CreateViewRequest.ViewDescriptor viewDescriptor = new
CreateViewRequest.ViewDescriptor( new EObjectAdapter(actImpl ), Node.class,
null,
//the actImpl is the element I just created in DiagramA, I want to creat the
shortcut in DiagramB using the element from DiagramA
ProcessDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT); CreateCommand
command = new CreateCommand(editingDomain, viewDescriptor,
targetdiagramImpl) {
protected CommandResult doExecuteWithResult(
IProgressMonitor monitor, IAdaptable info)
throws ExecutionException {
CommandResult result = super.doExecuteWithResult(monitor, info);
View view = (View) ((IAdaptable) result.getReturnValue())
.getAdapter(View.class);
if (view != null && view.getEAnnotation("Shortcut") == null) {
//$NON-NLS-1$
EAnnotation shortcutAnnotation = EcoreFactory.eINSTANCE
.createEAnnotation();
shortcutAnnotation.setSource("Shortcut"); //$NON-NLS-1$
shortcutAnnotation.getDetails().put(
"modelID", ProcessDiagramEditPart.MODEL_ID); //$NON-NLS-1$
view.getEAnnotations().add(shortcutAnnotation);
}
return result;
}
};
try {
OperationHistoryFactory.getOperationHistory().execute(comman d,
new NullProgressMonitor(), null);
} catch (ExecutionException e) {
ProcessDiagramEditorPlugin.getInstance().logError(
"Unable to create shortcut", e); //$NON-NLS-1$
}
