Problems encountered in the model [message #1834645]

Hi all,

I have created a UML profile as follows:

index.php/fa/39301/0/

I tried to generate an ecore model, but the genmode has the following error:

index.php/fa/39302/0/

Do you know what the issue might be?

Thank you!

Hi,

It looks like you're trying to generate there UML métalloïdes in addition to your profile. You need to référence the UML generator model instead from your genmodel. Otherwise, you will have a profile that can only be used with your private UML and not the common implementation.

Hi Christian,

Thank you for your answer. I am new to Papyrus, so could you please provide a more detailed answer on how could I do that?

Thank you very much!

This isn't really a Papyrus concern. It's an EMF/UML2 thing.

When you "load" the source model (your profile) in the GenModel editor, there's a page in which you have to choose which EPackages to generate (the top portion of the page)
and which to reference to their own existing GenModels (the bottom portion). You need to make sure that you have the UML GenModel from the Eclipse UML2 project in the bottom part
and select it with the checkbox. If you are working in a Papyrus installation of some kind (Eclipse Modeling package or a Papyrus RCP) then it should be available.

HTH,
Christian

Thank you! I was able to fix that. These are the packages that I generated and the ones that I referenced.
index.php/fa/39303/0/

However, now I get another issue.
index.php/fa/39304/0/

You definitely also should reference the Ecore genmodel, not generate your own copy of Ecore. In general, if you can reference an existing generated model, it is best for interoperability to do so.

I have no information about the error markers on the elements of the Corona package. These errors could be pretty much anything, but EMF's Ecore validation is pretty good about making error messages that explain themselves.

Ok, so after trying what you said, I do not get any more errors in my genmodel. However, what I am trying to do is automatically generate an XText grammar for it. With the above approach where I generate all packages but Corona, when I generate the XText grammar., I get some errors.
This is the code I get.

index.php/fa/39306/0/

And the errors I get are as follows:

Line 11, same on Line 30
Multiple markers at this line
- extraneous input '|' expecting RULE_ID
- Couldn't resolve reference to EClassifier 'EString'.

Line 12
EString cannot be resolved to a rule

Line 33
Multiple markers at this line
- missing RULE_ID at ':'
- The rule 'EDataType' may be consumed without object instantiation.
Add an action to ensure object creation, e.g. '{null}'.
- Cannot create type 'EDataType' in alias null

Hi

As as been pointed out to you many times already you need to provide a repro.

Clearly your initialization that you decline to share with us is defective otherwise you would not have a problem.

FRom your log I can only observe that the use of file:/ is usually very bad news. You should be using platform:/resource/.... but you provide no means for use to see what you are doing.....
