Sorry, being more specific, i've created an Action that have:

public void run() {
try{
final HiperioncadCreationWizard theWiz = new
hiperioncad.diagram.part.HiperioncadCreationWizard();


final Shell shell =
RoxUIPlugin.getDefault().getWorkbench().getActiveWorkbenchWi ndow().getShell();
final WizardDialog dialog = new WizardDialog(shell, (IWizard) theWiz);
dialog.create();

theWiz.init(RoxUIPlugin.getDefault().getWorkbench(), selection);
dialog.open();


}catch(Exception e){
e.printStackTrace();
}
}


but i keep getting this:

java.lang.NullPointerException

Hello Julia,

Can you take a look on generated ???InitDiagramFileAction ? Looks this is
implementation of such action.

Alex,
the ???InitDiagramFileAction implements an IObjectActionDelegate and not
an IAction.
Because of this it does not implement the setActivePart method that the
InitDiagramFileAction needs..

How can i get the active workbench editpart in a common Action? is that
possible?
im trying to call the whole creation (ecore and diagram) from a simple
menu in my plugin, to ease the process to the final user (will click New
project, then New Diagram rather than New project, then right click on
the project, new, Example, Diagram)

if i could get the wizard to work from the action would be perfect! ^^

can you help me?
Thanks!

Hello Julia,

You can take a look on existing implementations of IAction interface dealing
with IObjectActionDelegate - org.eclipse.ui.internal.handlers.ActionDelegateHandlerProxy.
In initDelegate() it is getting active part with the following code snippet:


final IWorkbenchPage page = window.getActivePage();
activePart = page.getActivePart();

window instance you can get using: PlatformUI.getWorkbench().getActiveWorkbenchWindow()

Well, I think the selection is null (you can check it in the debugger). You
should create StructuredSelection instance passing desired file as a parameter.
Then you are calling popup menu on some file the selection is equals to this
file, so corresponding parameter will be passed to ???InitDiagramFileAction...

Hi Alex and Julia.

First, thank you Julia for posting your solution!

Second, is it possible to create the diagram without launching the
wizard? (The action creates a new diagram with default values)

I have a follow up on this. Would it be possible to:
1. Create an action which opens a XYZdiagram.
2. Then loads that diagrams resource together with the diagram the
action was lanched from?

Diagram Partitioning does this. There is some code in the
opendiagrambehavior that syncs the resources. Maybe this code could be
made to work in an action?

That would be very cool!

Hello Tomas,

Sorry, did not get the quiestion.
If you need this question - just copy the code from generated OpenDiagramEditPolicy
- it should contains all you need to open an editor for the diagram file.
By default parent- and child- diagrams will be stored in the same EMF Resource,
so parent diagram will be automatically loaded into the corresponsing ResourceSet
on openning child- one.

Ok. Sorry for explaining unclear. I have 2 different diagrams. I want to
launch one of them from a popupaction (attached to an element in the
other diagram)


If you need this question - just copy

Ok. Guess It is this:
for (Iterator it = diagramFacet.eResource().getResourceSet()
..getResources().iterator(); it.hasNext();) {
Resource nextResource = (Resource) it.next();

if (nextResource.isLoaded() &&
!getEditingDomain().isReadOnly(nextResource)) {
nextResource.save(EditorDiagramEditorUtil .getSaveOptions());
}

}

I see. These diagrams are not parent/child (they are unrelated). Is this
still possible?


Thanks for helping!

Well, OpenDiagramEditPolicy will put new "unrelated" diagram for the diagram
element you double-click on into the same diagram Resource, so it is possible.
If you need to store it in a different resource - you should modify DocumentProvider
to preload this resource on creating new instance of EditingDomain.

Where does RoxUIPlugin come from? What kind of class is it?

Sure! just copy a code from diagram partitioning into your own action.

Thanks for helping (again) Alex :)

I've basically just copied the code in (as you can see below). The only
thing that gave an error was:
EditPart targetEditPart = getTargetEditPart(request);
so I replaced it with:
EditPart targetEditPart = selectedElement;

My question is:
What do I put in the run method? - I guess the getOpenCommand have to be
called.. but with what kind of reqest as parameter?

Tomas

That's right!

diagramFacet is a kind of reference from original diagram node to the associated
diagram. In the sample of code you pasted here you are creating new diagram
and associating this newly created diagram with the diagram node via diagramFacet.
On next execution of this action you can check if corresponding association
was already created and use existing diagram instead of openning new one.

You can get diagramFacet instance from the original diagram element (EditPart)
by calling
(HintedDiagramLinkStyle) ((View) EditPart.getModel()).getStyle(NotationPackage.eINSTANCE.getH intedDiagramLinkStyle())

Thanks! That got me a lot closer to a working solution. Now, however,
when I launch the action - I get a message that the action is unavailable.

Attaching the code.

This now kinda works. It opens an editor of the same type as it's self.
So the final obstacle is to get it to open another type of editor. I
changed getEditorID - that worked - But the new editor uses the same
diagram element as the first editor (wrong kind).

I guess this has to do with diagramFacet being set with the selected
element:
diagramFacet = (HintedDiagramLinkStyle) ((View)
selectedElement.getModel()...

How can I make a new diagram element of the right kind?

Hello Tomas,

AFAIU you have to choose correct diagram element while creating new diagram
- see OpenDiagramEditPolicy.intializeNewDiagram(). getDiagramDomainElement(),
getDiagramKind(), getPreferencesHint() methods are used there. You have to
modify these methods in accordance to return correct results for different
diagram type.

The rest should be working as is (taking into account getEditorID is already
changed). If you need to associate different diagrams with the same diagram
node then you have to attach several HintedDiagramLinkStyle instances to
each node and initialize/process them differently.

Hi again!

I've tried twisting and hacking on this for quite some time now, but I
can't seem to nail it. Basic steps are: 1. Copy methods from a
OpenDiagram policy. 2. Get diagramfacet 3. Adjust Methods to point at
right kind of diagram.

I'm attaching the body of my action (without selectionChanged etc.). In
it's current state it won't start.

If you or anyone else have time to point out errors, I'd be very
grateful for it!

Hello Tomas,

I suggest you debugging intializeNewDiagram() method to see which element
will be used as a "diagramDomainElement" in createDiagram() method call.
