Description rfreude 2005-06-22 13:23:45 UTC 
If two independant instances of NBMDRepositoryImpl create an extend with 
instanciating MOF an exception occurrs (only with memory storage - with btree 
storage it works): 

HashMap args;

// First Repository
args = new HashMap();
args.put
("storage", "org.netbeans.mdr.persistence.memoryimpl.StorageFactoryImpl");
args.put(BtreeFactory.STORAGE_FILE_NAME, "first");
MDRepository repository1 = new NBMDRepositoryImpl(_args);

// Second Repository
args = new HashMap();
args.put
("storage", "org.netbeans.mdr.persistence.memoryimpl.StorageFactoryImpl");
args.put(BtreeFactory.STORAGE_FILE_NAME, "second");
MDRepository repository2 = new NBMDRepositoryImpl(_args);

// Creating extends in both repositories
repository1.createExtent("foo");
repository2.createExtent("bar");

Results in:

Comment 1 Martin Matula 2005-06-28 17:50:38 UTC 
I've looked at the code and it seems it should work when you set a different
STORAGE_ID for these different repositories. The storage ID serves as the prefix
of MOF IDs generated by the storage.
To set them, replace BtreeFactory.STORAGE_FILE_NAME with
StorageFactoryImpl.STORAGE_ID in your code.

Please reopen this issue if it does not work and provide the log as an attachment.
