Properties view doesn't work for DnD element [message #1486753]

Hi everyone,

I'm newbie in modeling world and Graphiti, and I am trying to create simple RCP application with Graphiti Diagram.

All of my business objects are saved into one xmi file, which I can see and edit from the tree view.
I have implemented properties view for all my elements, and it works as I expected, but when I DnD business element from the tree view into diagram, and change any of its attributes through properties view, I'm getting Null Pointer Exception for my TransactionalEditingDomain.

Here is my part of code:

 if (m_componentDescription.isFocusControl()) {
      final PictogramElement pictogramElement =  getSelectedPictogramElement();
      final Component component = (Component) Graphiti.getLinkService().getBusinessObjectForLinkedPictogramElement(pictogramElement);

      final TransactionalEditingDomain editingDomain = TransactionUtil.getEditingDomain(component); //here I'm getting exception
      editingDomain.getCommandStack().execute(new RecordingCommand(editingDomain) {...

Can anyone help me with this ?

Thanks in advance...
Djordje

Djordje,

have you seen question 3 in our FAQ? That might help in building that.
https://www.eclipse.org/graphiti/developers/faq.php

You need to use the editing domain of the editor (get it from DiagramEditor)
and use that for modifications if you have a property sheet associated to
the diagram. TransactionUtil will not be able to provide the right editing
domain in that case.

Michael,

Thank you for your reply.

I would be very thankful if you could give me any example of editor editing domain usage.
I have tried to use getDiagramEditor method, but this method is deprecated. Which method should I use instead ?

Thank you in advance...

Djordje,

I gues you have a GFPropertySection, right? There is a method
getDiagramContainer you should call that will return the editor in the end
(DiagramContainers are any kind of UIs that can hold a diagram, e.g.
editors, views).

Michael,

Again, Thanks for your reply...

Yes I have GFPropertySection, and I have found method you mentioned above,
but what should I do next to get editing domain?

Djordje,

well, after that you can use the editing domain to execute your change.
Something like:

editingDomain.getCommandStack().execute(command);
where command is a subclass of EMF RecordingCommand.

HTH,
Michael
