Bug with diagram saving (and opening) [message #1728182]

Thu, 31 March 2016 11:51

Eclipse User

Hi, i'm sorry to bother you so much but I think that I have a bug that I can't manage to resolve.

The problem is that Sirius is unable to reload a saved diagram once eclipse has been closed.
I don't know if it is a Sirius bug or just me that have done something wrong.

Here is the steps to the bug
1 - Generate the genmodel from the XSD
2 - Generate the model/edit/editor code from the genmodel
3 - Launch a new runtime
4 - Create the viewpoint specification project and define the odesign
5 - Create a new Modeling Project
6 - Create a new model with the wizard of the editor (generated by the genmodel) in the previously created Modeling Project
7 - Link the viewpoint to the Modeling Project
8 - Create a new representation diagram
9 - Save that diagram
10 - Close eclipse
11 - Reopen eclipse
12 - This is what you get at this point : index.php/fa/25488/0/

Here is the stacktrace :

It seems that it is a known bug (https://bugs.eclipse.org/bugs/show_bug.cgi?id=447150) but once again i'm not sure, it might be me that have done something wrong.

is there any fix ?

Thanks,
Alex

I tried to generate the model/edit/editor code with the genmodel from the family example and it appears that I don't have any saving bug. We can conclude that the problem does not come from my eclipse configuration

So I guess that it comes from my genmodel (itself generated from an xsd constraint file), but I still can't figure out why it is not generating correcly my code.

Ok I am almost 100% sure it is a Siruis generation bug because when I generate my model/edit/editor with the EEF plugin I don't have this bug anymore. I tried to do a file comparison but coulnd't find any relevent differences. Strange...

I had the same problem. I was working on Eclipse Mars (4.5.1). After many frustrating trials, downloading Obeo Designer and using it as a design environment solved my problem. Hope this information helps other users of Sirius.

I am facing the same problem. I switched from Mars.2 to Neon using Sirius 4.0.0 but the issue did not disappear. After this happens, the model Explorer does not show the details of my model any more. The file node in the model Explorer has no children. Maybe this will help someone to solve the issue?

Hi

Have you checked the error log and tried validating.

I found that any deficiency in the model locked out the Model Explorer,
and it needed a good restart after fixing the model before children
reappear.

Regards

I also had this issue. After a little digging i was able to solve it for me. Turned out I was using sub-EPackages in my ecore model and you should never do that. Since I extracted them to separate ecore files, everything works fine.

in my model also i have sub-E Packages but there is a relation between each sub-E Packages .If i extract them to separate ecore files, whether the relation still exists or not. How can we extract them to separate ecore files.

By "Load Resource" on a ecore file you can "import" a separate ecore file and make the contents known. You also can add multiple ecore files to your .genmodel

It is a annoying to extract all sub-packages but this should resolve the error. (atleast it worked for me)
