Re: [xmlblaster] crash in c++ PublishDemo

["Juergen Prinz" <Juergen.Prinz at avitech-ag.com>]

After testing further on, I encountered another problem.

The update of the published data shows always contentSize == 0.
When enquiering on the Blaster-Window, the content of the oid is shown
correctly.
When testing the PublissDemo / SubscribeDemo i got :

TRACE DefaultCallback-prinz Received message [c++-demo] from publisher <session
name='client/postgres,\' timeout='86400000' maxSessions='10'
clearSessions='false'/>

TRACE DefaultCallback-prinz going to invoke client specific update
