A) Method Body
public Multiplex createMultiplex(
String name, Float maxAvailBitRate, Integer transportStreamId,
UUID carrierId, Integer startSID, Integer endSID)
throws Exception {
//Asset asset = DomainPackage.eINSTANCE.getDomainFactory().createAsset();
Multiplex mul = DomainPackage.eINSTANCE.getDomainFactory().createMultiplex() ;
//Data Population
mul.setName("onesat");
mul.setMaxAvailableBitRate(2F);
mul.setTransportStreamId(1);
mul.setCarrierContentId(UUID.randomUUID()); // -------- At this line, exception comes
mul.setStartSID(3);
mul.setEndSID(4);
MultiplexDaoImpl.getInstance().saveMultiplex(mul);
return mul;
}
B)
During debugging, it leads to this function.
------------------------------------------------------------ ---------------------------
public Object createFromString(EDataType eDataType, String initialValue) {
switch (eDataType.getClassifierID()) {
case DomainPackage.UUID:
return createUUIDFromString(eDataType, initialValue);
case DomainPackage.CARRIER_TYPE:
return createCarrierTypeFromString(eDataType, initialValue);
case DomainPackage.CARRIER_CONTENT_TYPE:
return createCarrierContentTypeFromString(eDataType, initialValue);
default:
throw new IllegalArgumentException("The datatype '" + eDataType.getName() + "' is not a valid classifier");
}
}
------------------------------------------------------------ --------------------------------------------------
C) Stack Trace
java.lang.IllegalArgumentException: The value 'da6530d2-e847-4877-a874-1c8fee74611a' is invalid.

To be honest I am not sure why this happens. Have you debugged into the EFactoryImpl.createFromString? (I see only stack
traces but no debug info).
Really I always debug into the EMF/Hibernate/etc code if I meet these type of errors. It takes only a few minutes and it
gives you great insights.
btw, if you want to be sure that I look at your post you need to prefix the subject with [Teneo]

MT>> Yes it is a classic dilemma, if you already have a schema then the only way is to provide an extensive
annotations.xml which maps EMF models to the existing schema. That's what I would do, if the db schema is leading then
you are can be forced to adapt the model a bit so that it fits to the database schema.
Btw, did you know that you can also generate testdata with just a model:

Hi,
I don't recall your model, maybe you have a join table where the statelliteId is used. It does not matter for hibernate,
you can use HQL or criteria querying and it will automatically take care of joining if a join table is involved.
Note that if you save and query in one transaction that to get generated id's in the database you have to flush before
querying.

the referenced object is not part of the resource and the resource has no way of getting to the object.
