The package is needed but is not accessible from the generator model [message #1116704]

Hello guys,

I have a file called arquivo.emf that depends on BPMN20.ecore right? The BPMN20.ecore depends on 3 others files called BPMNDI.ecore, DC.ecore and DI.ecore.

When I click on arquivo.emf and after on Eugenia -> Generate GMF Editor, the following problems arise:

The package platform:/resource/tarcisio/model/DI.ecore is needed but is not accessible from the generator model

The package platform:/resource/tarcisio/model/DC.ecore is needed but is not accessible from the generator model

I don't know how to solve this problem.

Thank you.

Hi Tarcisio,

I'm afraid that as noted in the Troubleshooting section of [1], Eugenia doesn't work well with Ecore metamodels that span across multiple files/sub-packages.

Cheers,
Dimitris

Dimitri, Eugenia works with more than one metamodels.

I already did a project where A.ecore depends on B.ecore and it works perfect.

Now, I have the problem that I told you before :/

I'm generating the file.genmodel manually, is there any way when I click on Eugenia -> Generate GMF Editor, the file.genmodel that I created before don't be replaced?

To prevent Eugenia from generating your .genmodel you need to do the following:

- Generate your .genmodel manually
- Right click your Ecore metamodel and select Eugenia -> Generate GMF graph, tool and map models
- Right click the generated .gmfmap model and select Create generator model
- Right click the generated .gmfgen model and select Eugenia -> Synchronize GMF gen model
- Right click the .gmfgen model again and select Generate diagram code

Cheers,
Dimitris

Thank you Dimitris!

It works, but the attributes from the class VariationPoint doesn't appears.

Hi,

Could you please put together a minimal example [1] we can use to reproduce this?

Cheers,

- Import the tarcisio project;
- Copy and paste the arquivo.ecore and arquivo.emf files in the model folder;
- Click in BPMN20.genmodel and click in Generate Model code and after Generate Edit Code;
- From the arquivo.ecore file, generate the arquivo.genmodel file manually.
- After, click in arquivo.genmodel and click in Generate Model code and after Generate Edit Code;
- Some erros will appears, then correct the errors using imports;
- Generate manually all others need files, arquivo.gmfgraph, gmftool, gmfgen, diagram, ect;
- If some erros appears, correct using imports;
- Run the project;
- You will see that when you put a variation point node, the attributes doesn't appears, but if you are using a tree everything works normally;

Hi,

Should there be a copy of arquivo.ecore/arquivo.emf in the zip file?

Cheers,
