[news.eclipse.tools.emf] Re: [CDO] How can I get information on new obje

[Eike Stepper <stepper@xxxxxxxxxx>]

Hi Anders,

You can receive the information about detached objects via 
CDOSessionInvalidationEvents if 
CDOSession.Options.isPassiveUpdatesEnabled == true. A CDOView can only 
deliver CDOViewInvalidationEvents with information about objects that 
are loaded by this particular view. If you need this information for 
particular objects under all circumstances you must ensure that these 
objects are loaded. Holding application pointers to these objects 
(HashSet?) can do this.

Cheers
