lots of errors in ocl file [message #1765894]

Hi,

When I open an .ocl file in eclipse, I have several errors (Unresolved " 'eshop', etc.). I attached the related screenshots for the program and installed ocl software.
I also registered the metamodel. However, the errors didn't disappear.

Hi

Have you looked at any of the Complete OCL examples? You need an import statement.

'registration' was a solution in the old Eclipse OCL support that was only available in conjunction with a Java API.

The import statement overcomes the total inability of Complete OCL as specified to be used with anything. One day OMG OCL will endorse an import statement.

Thank you very much indeed.
When I use import statement, many of the errors disappear. However, I still have 2 errors and one warning. I attached screenshots of the program.

Hi

I don't know why you do

import eShop : 'http://www.example.com/'

For which the error message is:

Multiple markers at this line
- Unresolved Namespace 'http://www.example.com/'
- The required feature 'pivot::Import::importedNamespace' of 'eShop : «null»' must be set

If I do

import eShop : 'eShop.ecore'

it works fine.

Since in the EPackageRegistry the uri of this ecore is http://www.example.com, I used this address in the import statement.

When I test eShop.ecore instead of this address, I have the same error. I also change the uri of this ecore to eShop or eShop.ecore but the error doesn't disappear.

Hi

The EPackageRegistry is useful for applications that use installed facilities. Editors generally use dynamic models. Certainly eShop.ecore is a dynamic model. I have no idea how you actually poke the EPackageRegistry .

Since an import works for me and you do not tell me precisely what you do, I cannot help tell you what you did wrong.
