Diagram disappears after saving when one tries to edit [message #1042436]

Hi.

I developed a custom editor, for which I contributed a customized EditorInput and where I reimplemented init in order to be possible to load directly the model file and generate diagram from it if necessary.

Everything runs ok. After opening I can edit and create new objects, however after Saving, the editor becomes unusable, graphic elements disappear, and I can't create anything.

Do you know what can be happening. Is this a symptom of issues with recordsets transactionaleditingdomains?

Thanks in advance

Rui,

not sure what happens here. Did you check what's being persisted on disk?

I haven't tried adding things to the diagram as you did it. There is an
example in the finished tutorial plugin in the SDK that add a context menu
entry to the project explorer that creates a new diagram and populates it
with some initial content, maybe that would be an option? See here:

Hi. Thanks.

That's the example I used. But I changed somethings such as:

I have an editor extending Graphiti DiagramEditor.
I have a custom class extending DefaultBehaviour which creates editingdomain. /resourceset

When I ask a Model file to be open, the init method trigers the creation of a custom diagraminput which contains naturally diagramURI, and also modelURI.

The diagramURI is created from modeluri changing the extension. Both are added to the diagrameditor resourceset.
Meanwhile, it is created the diagram and added to the respective resource, And the same way as it is in tutorial I dark-process my model elements. The diagram opens with everything but when I save it becomes zombie.

The content of the files is alright.

I could notice that I cannot do updates or layouts during dark-processing.

The dtp that I use for darkprocessing is not the one of the editor, because editor gives me a null DTP. So I create a new one via Graphiti API.

Thanks again

Rui,

not sure, but maybe the creation of the diagraminput is the issue. There you
might need to distinguish between creating a new diagram and opening an
existing one?
