[xmlblaster] Subscribe/Unsubscribe exception

[Cyrille Giquello <cyrille at giquello.com>]

Hello,

I come here because of an exception comes when unsubscribing.

The scenario is:
- The app subscribe with a xpath query.
- the app wait a while then unsubscribe from that previous subscribtion.
- Note that there is no message in xmlBlaster, so the query never match.

When calling unsubscribe a exception is throwed :

ERROR RequestBroker-OidUnknown2] Can't access subscription, unSubscribe 
failed, your supplied key oid '' is invalid

The subscribtionId is ok, the query to. I really don't understand why 
that happen.

Here is the log:
