Hello,

Following some tutorials (I'm a newbie in this area), I succeeded to save a EMF model that contains EMaps with teneo / hibernate in a mySql DB:

The 'save' seems to work only if I set the option EMAP_AS_TRUE_MAP to 'false'.

final Properties props = new Properties();
props.setProperty(Environment.DRIVER, "com.mysql.jdbc.Driver");
props.setProperty(Environment.USER, "root");
props.setProperty(Environment.URL, "jdbc:mysql://127.0.0.1:3306/" + dbName);
...
props.setProperty(Environment.HBM2DDL_AUTO, "create");

props.setProperty(PersistenceOptions.CASCADE_POLICY_ON_CONTAINMENT, "ALL");
props.setProperty(PersistenceOptions.CASCADE_POLICY_ON_NON_CONTAINMENT, "MERGE,PERSIST,REFRESH");
props.setProperty(PersistenceOptions.EMAP_AS_TRUE_MAP, "false");
...
HbDataStore dataStore = HbHelper.INSTANCE.createRegisterDataStore(dataStoreName);
dataStore.setEPackages(new EPackage[] { SysmodPackage.eINSTANCE });
dataStore.setDataStoreProperties(props);
dataStore.initialize();
...
SessionFactory sessionFactory = dataStore.getSessionFactory();
{
    Session session = sessionFactory.openSession();
    session.beginTransaction();

    Long l = (Long) session.save(model);
...


but I don't know how to reload this model from the database.

I tried a 

...
SessionFactory sessionFactory = dataStore.getSessionFactory();
{
    Session session = sessionFactory.openSession();
    session.beginTransaction();
            
    model = (Model) session.load("Model", l);


but it fails with the following error when it reaches my first map (myMap)

Any idea how to reload a model that contains maps and that was saved with EMAP_AS_TRUE_MAP=false ?

Thanks in advance for your support,

Best regards,
Bernard.

I wonder, is this the complete stacktrace? There should be an underlying exception which is there also.

You can also debug into the EListPropertyHandler, put a breakpoint at line 457 to see what exception gets thrown.

Also what happens if you set EMAP_AS_TRUE_MAP to true?

Hello Martin, and thank your for your support.

To answer to your questions / remarks:

1) Problem with the load: There was indeed a second part of the stack trace that I forgot to post, and here is it:
...
Caused by: java.lang.IllegalArgumentException: Can not set org.eclipse.emf.common.util.EMap field xxx.sysmod.impl.ModelImpl.myMap to org.eclipse.emf.teneo.hibernate.mapping.elist.HibernatePersistableEList

	... 124 more


2) If I do not force EMAP_AS_TRUE_MAP to false, then even the session.save(model) fails with following errors:

Some info. about my config, just in case:
- Eclipse 3.7
- Teneo 1.2.0.v201107080556
- Hibernate 3.6.0.201107071603

Hope that helps ...

Hi Bernard,
It seems that Teneo does not detect that your field is an EMap field. Can you post your ecore model? If it is
confidential then you can also email it directly to me.

Bernard.
