Hello

I try to implement the save as functionality. What I have to do now?

I would like to have the possibility to save the current diagram und model
state in a new file.

I know following: I have to override the method isSaveAsAllowed and doSaveAs
from the class DiagramDocumentEditor.

My problem is: I don't know what I have to do now.

I can not copy both files an save it under a new name, because the diagram
file have a relationship to the modelfile.

Thank you for your help

Hello Urs,

See generated ???DocumentProvider.doSaveDocument() - saveAs is implemented
there (only diagram file model is copied now, so you can extend it to copy
domain model as well).

Hello Alex

Thank you for your answer

Ok, I can now copy the two files. My problem is actual the relationship
between the two files. If I only copy the files, the diagram file have the
relationship to the original modelfile. Have you a idea, how to bring the
two new files together?

Have a good weekend

Urs

Hello Urs,

As a simple solution you can just assign existing model content to new resource
and then save only this new resource (without saving original one model information
will not be removed from there) like:

Resource newModelResource = diagramDocument.getEditingDomain().getResourceSet().createRe source(newModelResoruceURI);
newModelResource.getContents().addAll(diagramDocument.getDia gram().getElement().eResource().getContents())
newModelResource.save(EcoreDiagramEditorUtil.getSaveOptions( ));

Hello Alex

Thank you for your answer

No, that is not my problem. I can copy the model and diagram file.
The situation:
Model file origModel
Diagram file origDiag

Now I copy the two and I have now two new file:
Model file copyModel
Diagram file copyDiag

The Problem is now. The file copyDiag has a reference to origModel.

<element xmi:type="model.model:AuxVariable"
href="origModel#//@allAuxVariable.0"/>

I make the copy from the model and diagram by using the methode
EcoreUtil.copy
After that I add the EObject to a resource and the Diagram to a resource and
save it.

Now, I found no way to replace this href with the correct copyModel ref.
Have you any idea.

Thank you for your help.

Hello Urs,

Right. This is because original diagram was referencing old model.. If you
MOVE domain model from original resource to new one then the all references
in loaded diagram (or even diagram copy) should be updated automatically.
Try using the code sniped I posted above before saving diagram resource copy.
