Importing an XTM 1.0 file with two associations (duplicate) which each 
have their own reifying topic fails with: "cannot reify more than one 
reifiable object".

Comment 3 by larsga, Jul 20, 2009

Customer reports that the fix did not work, and retesting with the RDBMS backend 
shows that the problem does indeed continue to exist there. Retesting with the in-
memory backend does not reproduce the problem.

We have tested XTM file import into database using XTMTopicMapReader.importInto() 
API and it succeeds the exection and data getting populated in DB.

But when we test Synchronize update of XTM file into database which contains two 
associations(duplicate) and corresponding two reified topics using 
TopicMapSynchronizer.update() API, all reified_id columns in many tables still 
contains NULL values.

Hi Joe,

Excellent. That means that this issue (#77) is solved.

> But when we test Synchronize update ...

Ok. That means we still have an issue in TMSync. That is a separate issue, though. 
Please report it separately.
