Hi Hans,
I have a testcase which tests this and it works. This exception can occur when you try to save an
object in two different sessions. This occurs for example if you have references between objects in
different resources. If you save one resource then the refered object in the other resource is also
saved, when you then save the second resource this error occurs. Also the name of your testcase
seems to refer to this.
If this is the case then you can use a SessionController (url probably truncated by line break):
http://www.elver.org/hibernate/hibernateresources.html#Shari ng+one+Session+between+Resources%2C+One+transaction+when+sav ing+multiple+resources
to share a session between resources.

Hi Martin,
I save everything in a single resource. The name of the test case is
just because I changed an old test case when trying to check out if I
can reproduce the Exception with a test case.
The funny thing is, that when I'm commenting out the marked lines down
below and run the test case twice, the second time it fails.
If you want to, I could provide you the project containing the testmodel
and the test case.
For now, here is my full testcode:
final String dataStoreName = "enumtest";
final HbDataStore dataStore =
HbHelper.INSTANCE.createRegisterDataStore(dataStoreName);
EPackage[] packages = new EPackage[] {TestmodelPackage.eINSTANCE};
dataStore.setEPackages(packages);
Properties properties = new Properties();
properties.setProperty("hibernate.connection.driver_class", "com.mysql.jdbc.Driver");
properties.setProperty("hibernate.connection.url","jdbc:mysql://127.0.0.1:3306/enumtest");
properties.setProperty("hibernate.connection.username","root ");
properties.setProperty("hibernate.connection.password","system ");
properties.setProperty("hibernate.dialect","org.hibernate.dialect.MySQLInnoDBDialect ");
dataStore.setHibernateProperties(properties);
dataStore.initialize();
EditingDomain domain = new AdapterFactoryEditingDomain(new
ComposedAdapterFactory(ComposedAdapterFactory.Descriptor.Reg istry.INSTANCE),new
BasicCommandStack());
String uriStr = "hibernate://?" + HibernateResource.DS_NAME_PARAM +
"=enumtest";
URI uri = URI.createURI(uriStr);
Resource dbResource = domain.getResourceSet().getResource(uri, true);
TestClass element1 = TestmodelFactory.eINSTANCE.createTestClass();
element1.setEnumProperty(TestEnum.ITEM1_LITERAL);
dbResource.getContents().add(element1);
// Commenting the following lines out brings up an Exception when
// running the test case twice
TestClass element2 = TestmodelFactory.eINSTANCE.createTestClass();
element2.setEnumProperty(TestEnum.ITEM1_LITERAL);
dbResource.getContents().add(element2);
dbResource.save(null);
reetings,
Hans

Hi Hans,
Can you send me the test project and test case?
So if you don't comment out the lines then running twice does not result in an error?

Hi Martin,
I'll send you the Project soon via mail. When not commenting out these
lines I can't even run the test case once without an exception.

Hi Hans,
I tested this and with me the error was that the enum property was set to unique, so I got a unique
constraint violation.
This was caused by a bug that the unique property of an EAttribute was still being used for enum and
lob. I have entered a bugzilla for this:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=162256
I have committed a fix, this will be in the next build (probably friday).
Can you check if setting the unique property of the EnumProperty to false helps? You need to
regenerate the sources for Teneo to see the new unique value as it reads the runtime model.

Hi Hans,
I have a testcase which tests this and it works. This exception can occur when you try to save an
object in two different sessions. This occurs for example if you have references between objects in
different resources. If you save one resource then the refered object in the other resource is also
saved, when you then save the second resource this error occurs. Also the name of your testcase
seems to refer to this.
If this is the case then you can use a SessionController (url probably truncated by line break):
http://www.elver.org/hibernate/hibernateresources.html#Shari ng+one+Session+between+Resources%2C+One+transaction+when+sav ing+multiple+resources
to share a session between resources.

Hi Martin,
I save everything in a single resource. The name of the test case is
just because I changed an old test case when trying to check out if I
can reproduce the Exception with a test case.
The funny thing is, that when I'm commenting out the marked lines down
below and run the test case twice, the second time it fails.
If you want to, I could provide you the project containing the testmodel
and the test case.
For now, here is my full testcode:
final String dataStoreName = "enumtest";
final HbDataStore dataStore =
HbHelper.INSTANCE.createRegisterDataStore(dataStoreName);
EPackage[] packages = new EPackage[] {TestmodelPackage.eINSTANCE};
dataStore.setEPackages(packages);
Properties properties = new Properties();
properties.setProperty("hibernate.connection.driver_class", "com.mysql.jdbc.Driver");
properties.setProperty("hibernate.connection.url","jdbc:mysql://127.0.0.1:3306/enumtest");
properties.setProperty("hibernate.connection.username","root ");
properties.setProperty("hibernate.connection.password","system ");
properties.setProperty("hibernate.dialect","org.hibernate.dialect.MySQLInnoDBDialect ");
dataStore.setHibernateProperties(properties);
dataStore.initialize();
EditingDomain domain = new AdapterFactoryEditingDomain(new
ComposedAdapterFactory(ComposedAdapterFactory.Descriptor.Reg istry.INSTANCE),new
BasicCommandStack());
String uriStr = "hibernate://?" + HibernateResource.DS_NAME_PARAM +
"=enumtest";
URI uri = URI.createURI(uriStr);
Resource dbResource = domain.getResourceSet().getResource(uri, true);
TestClass element1 = TestmodelFactory.eINSTANCE.createTestClass();
element1.setEnumProperty(TestEnum.ITEM1_LITERAL);
dbResource.getContents().add(element1);
// Commenting the following lines out brings up an Exception when
// running the test case twice
TestClass element2 = TestmodelFactory.eINSTANCE.createTestClass();
element2.setEnumProperty(TestEnum.ITEM1_LITERAL);
dbResource.getContents().add(element2);
dbResource.save(null);
reetings,
Hans

Hi Hans,
Can you send me the test project and test case?
So if you don't comment out the lines then running twice does not result in an error?

Hi Martin,
I'll send you the Project soon via mail. When not commenting out these
lines I can't even run the test case once without an exception.
greeting,
Hans

Hi Hans,
I tested this and with me the error was that the enum property was set to unique, so I got a unique
constraint violation.
This was caused by a bug that the unique property of an EAttribute was still being used for enum and
lob. I have entered a bugzilla for this:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=162256
I have committed a fix, this will be in the next build (probably friday).
Can you check if setting the unique property of the EnumProperty to false helps? You need to
regenerate the sources for Teneo to see the new unique value as it reads the runtime model.
