[CDO/EMF] Ecore SubPackages & CDOPackage reading [message #1021715]

Hi everyone.

I have an Ecore model with root & subpackage as :
xxx.yyy.model
xxx.yyy.model.subpackage

When CDO server starts, it reads PackageUnits from database doing :
SELECT unit, uri, parent FROM cdo_package_infos

It seems that my both packages (root & sub) have the same unit : xxx.yyy.model.

The problem is that read packages are put in a HashMap, so I obtains only one entry for both packages.

So it causes a NPE in MetaDataManager.loadPackageUnit() when trying to resolve package with id="xxx.yyy.model".

If I go down in stack strace in CDOPackageRegistryImpl(EPackageRegistryImpl).getEPackage(String), I obtain this for parameter nsURI="xxx.yyy.model"

ePackageDescriptor (CDOPackageInfoImpl) :
CDOPackageInfo[packageURI=xxx.yyy.model, parentURI=null]
CDOPackageUnit[id=xxx.yyy.model.subpackage, state=PROXY, ...]

Does CDO support ECore subpackages ??

Found this :

Changed mapping of CDOPackageUnit to prevent multiple records for the same CDOPackageUnit

On this page :

Will CDO 4.1 fix my problem ???

I really hope so, but you should definitely try it. I'm not aware of current problems with subpackages.

Please note that 4.0 is out of maintenance and 4.2 is very near ;-)

Cheers

Thanks for your reply Eike.

I tried 4.1-SR2, I can't definitely be sure it fixes my bug cause my previous database (HSQLDB) is aleady corrupted, but I've seen in debug that each PackageUnit is now associated with several PackageInfos containing all subpackages.

Wait and see if my database doesn't become corrupted anymore but all this stuff seems to be good Wink
