Create model from existing uml not working in Luna/Papyrus 1.0.0 [message #1407002]

Running Eclipse Luna / Papyrus 1.0.0 on Linux Mint 17 (Ubuntu 14.04).

I am trying to import the uml profile for RDF (version 1.1beta2 posted on the OMG website. I'd include a link, but this forum says: "You can only use links to eclipse.org sites while you have fewer than 5 messages."

Instructions seem to indicate that I would import the file into a project, navigate to it within the Model Explorer, then right click and initialize a papyrus diagram. (https://wiki.eclipse.org/Papyrus_User_Guide#Create_a_diagram_from_an_existing_uml_file).

Problem: The "Model Explorer" never shows the tree for existing uml files (created by Paprus or created externally). It shows "No model available", unless the diagram editor for the model is open and currently selected. The key is that the selected diagram editor controls what the Model Explorer displays, and since the uml file does not have a diagram yet, it can never be displayed. "Package explorer" does not have the option to initialize a papyrus diagram.

Possibly Related Problem: The "Model Explorer" never shows any tree for any uml files when the Modeling perspective is open. Switching to the Java perspective displays a tree in the Model Explorer.

Has the recommended method of importing externally defined UML models changed in the new version?

My "Possibly Related Problem" may be due to the fact that I was using the Modeling Perspective instead of the Papyrus perspective. I didn't notice the Papyrus option at first.

Found a post which suggests to navigate to the xml resource via the Package Explorer, right click, and create a new papyrus model. (https://www.eclipse.org/forums/index.php/mv/msg/149654/470453/#msg_470453) This creates a blank model 100% of the time on my test data (The Business Motivation Model v. 1.2, posted on the OMG.org site).

I did get the OMG XMI to import, sort of. My process was:

Replace the base element <xmi:XMI/> with <uml:Model/> from a blank papyrus model.
Delete the trailing <mofext:xyz/> tag which followed the package.
Change the <uml:Package/> item to <packagedElement type="uml:Package"/> ...
Change four upper bounds from 0 to 1.
Change a <type href="OMG URL reference to type"/> to href="platform://blahblah" when referring to a String.

After that, I can do a package import and use the OMG-defined model from my own models. However, I am noticing that the import was imperfect. Whatever wrote the OMG file appears to represent a multiplicity of "*" by omitting the lower bound and specifying an upper bound of "*". Papyrus/eclipse interprets this as "1..*".

I can fix it with the UML editor (the property editor looking thing), but I have yet to be able to create a diagram which directly edits this model.

Hi Bryce,

The wiki is outdated. To create a new Papyrus mdoel from an existing *.uml model:

- Select the *.uml file
- Go to File > New > Papyrus Model

Eclipse/UML2 and Papyrus should support the various OMG/XMI namespaces. However, Papyrus expects the *.uml file extension. So, replacing *.xmi with *.uml should be sufficient in most cases.

Depending on the models, there might be some additional refactorings required; e.g. I'm not sure how references to UML Primitive Types are handled (It seems you had issues with them)

Regards,
Camille

I'm sorry for bringing up this old post, but I'm currently facing more or less the same problems.
I'm trying to import an *.uml file into Papyrus, which I created using the "org.eclipse.uml2.uml" classes, but using the described workflow:

1. Navigate to *.uml file in Package Explorer
2. Right click
3. New > Other... > Papyrus Model

results in an empty editor for the *.di file. The Model Explorer View shows the contents of the *.uml file, but I have no idea how to convince Papyrus to display them in the editor.
Even if I create an *.uml file with Papyrus instead of using the "org.eclipse.uml2.uml" classes, I face the same problems when reimporting the file *.uml file with the described workflow. I'm not quite sure whether I'm missing something, but I would appreciate any hints on this topic.

Thanks in advance and kind regards
David

Hi, David,

Papyrus does not automatically create diagrams to visualize the
contents of your model.

You need to create diagrams (context-menu actions in the Model Explorer
and also available in the toolbar) and drag elements from the Model
Explorer into those diagrams to populate them.

HTH,

Christian

I found this thread and though great now I know why the *.di is empty. But for me when I open the Papyrus Perspective the Model Explorer is empty, no matter what I give focus to in the Project Explorer or inside a *.uml file. I checked Preferences and restore them to default but still nothing. What am I missing? I am on Juno 4.4.1 and Papyrus 1.0.2.201502181349
