I am having an operation with return type as tuple in my pivot based ECore.

i am getting following exception while i try to save the instantiation of Ecore model (the resource).

org.eclipse.emf.ecore.resource.Resource$IOWrappedException: The object 'org.eclipse.ocl.ecore.impl.TupleTypeImpl@1b12ee3 (name: null) (instanceClassName: org.eclipse.ocl.util.Tuple) (abstract: false, interface: false) (serializable: true)' is not contained in a resource.

do you have idea why it is so?

I have tried to save all defined tuple types in ressource and now do not get earlier mentioned exception.

But now when i try to evaluate using delegates then i get the following exception...

Hi,

I have been looking into test written for TupleType(test_TupleLiteralExp_checkTupleType). It uses TupleLiteralExp and TupleLiteralPart which i have not used with TupleType. Do you think it might be the cause?

My code is like
TupleType tt = org.eclipse.ocl.ecore.EcoreFactory.eINSTANCE.createTupleType();
EAttribute eAttribute1 = EcoreFactory.eINSTANCE.createEAttribute();
EAttribute eAttribute2 = EcoreFactory.eINSTANCE.createEAttribute();
eAttribute1.setName("first");
eAttribute1.setEType(EcorePackage.eINSTANCE.getEDouble());
eAttribute1.setName("second");
eAttribute2.setEType(EcorePackage.eINSTANCE.getEBoolean());
tt.getEStructuralFeatures().add(eAttribute1);
tt.oclProperties().add(eAttribute1);
tt.getEStructuralFeatures().add(eAttribute2);
tt.oclProperties().add(eAttribute2);
// set the type of operation as tuple
eOperation.setEType(tt);

Cheers,

Hi,

I have attached a plugin(developed in Kepler). It is very simple plugin with one package "tupletest1".
It contains file TestTuple.java. In this file an Ecore model is created programmatically consisting of one class. Class has one attribute(name = test, type = Real) and one operation(name=opt, type = Tuple(Real, Real), arguments=none).

The OCL statement for attribute is "let t : Tuple(a:Real , b:Real) = opt() in t.a*4" and the OCL statement for operation is "let t : Tuple(a:Real, b:Real) = Tuple{a=2, b=2} in t"

The class TestTuple is instantiated in class View.java(simple view onCreate instantiation for TestTuple is performed).

When i try to evaluate attribute using setting delegates then i get the following exception

org.eclipse.ocl.common.internal.delegate.OCLDelegateException: OCL evaluation result of 'temp::TestClass.test' is invalid

Do you have any clue wht tuple is problematic in the given code.

Cheers

Hi

You didn't specify how to run your code; Opening a Perspective named
Perspective is a very odd approach.

I have no idea why you are doing such low level model creation. It is
incredibly hard, but if you're going to ignore the higher level aids you
should expect to debug your own problems.

If you added a

Diagnostician.INSTANCE.validate(modelPackage);

you would have noticed a couple of

The feature 'eType' of
'org.eclipse.emf.ecore.impl.EOperationImpl@11db0bc{test.ecore#//TestClass/opt}'
contains a dangling reference
'org.eclipse.ocl.ecore.impl.TupleTypeImpl@129751d{#//}'
The feature 'eClassifier' of
'org.eclipse.emf.ecore.impl.EGenericTypeImpl@c7c79e{test.ecore#//TestClass/opt/@eGenericType}'
contains a dangling reference
'org.eclipse.ocl.ecore.impl.TupleTypeImpl@129751d{#//}'

Once you fix those, you will notice that your tuple parts are unnamed,
causing the operation lookup failure and so the eventual failure.

When writing very complicated stupid code expect the problem to be in
your code so debug it properly.

Now go back to your original messages and ask yourself how anyone could
have answered your question sensibly.

Regards

Ed Willink

Re: OCL Tuples in pivot [message #1162253 is a reply to message #1162198]

Sorry for giving incomplete information.
You can run the plug-in as Eclipse Application (menu Run->Run As->Eclipse Application).

The perspective/GUI is just for the testing... just ignore that.
Dangling reference problem is solved (i added tupletype in package).
I have also given names to tuple parts but still i am getting the same exception when i try to evaluate using dalegates.

Please check the attached project. Thanks!

Hi

I'm sorry. I have no more time to spend on your crazy code.

I understand that you are busy. I have created a simple ecore file. Please open the file in Kepler build. It contains one Class(TestClass) having one attribute(test) and one operation(opt). There is no validation error. Validation is successful, but when i try to instantiate the class (name = TestClass) then it give me the same error.

open the ecore in simple ecore model editor and right click the class(TestClass) and select "create dynamic instance", save the xmi file and open it in sample ecore reflective editor.

open first tree node for instance.

thanks for your time

Hi

Your model has a variety of problems, most notably the use of "(" in
names rather than EGenericType.

Basically you seem to be trying to workaround
https://bugs.eclipse.org/bugs/show_bug.cgi?id=392059,
https://bugs.eclipse.org/bugs/show_bug.cgi?id=401938.

This bug is getting really irritating; must be time to fix it.

Regards

Is this in your priority list? Do we expect it to be fixed in near future?

thanks for support!

Cheers,

Hi

It is my current coding activity.

But EclipseCon was last week.

This weekend we have a workshop to discuss directions for OCL 2.5.

So my coding activity is not 100%.

Hi,

I have tried the same example again and in the latest version (eclipse.buildId=4.4.0.I20140123-1600) and i am getting the same problem. Are tuples still problematic in the latest version?

Cheers,

Hi

It's still on my TODO list but not that close to the top I'm afraid.
