Hello,
I have a java application which intercepts events from an office bean
using the GlobalEventBroadcaster interface.
The problem is the following: my application will have different
instances of the bean running, and the GlobalEventBroadcaster intercepts
all events coming from all sources if I have understood properly, so I'm
not able to understand which document has been loaded on a onLoad event.
Now I'm able to find the name of the event, but I can't understand which
instance it is coming from.
My goal is to find at least the name of the file being loaded, or better
a unique ID identifying the instance of the bean which generated the event.
Any idea?
Thank you
bye
Here's the code of an example class (you have to change the URLs of the
