IMHO, You're taking the wrong approach by using reactors.
It's far easier to just scan the database when it is saved,
and update your external data there.
The only time I need to track changes to objects in 'near-
real-time', is when I need to update a user interface (like
a floating palette) to keep the view it displays in sync with
the contents of the drawing.
But, if the purpose is only to update external data like your
scenario, the better way is to just do it once when the file is
saved.

Hi All,
I am using ADT and Xml. When an object ( Doors & Windows) is added, modified or deleted from the drawing then i am writing that information to the Xml file by using the Reactors. But when UNDO and REDO commands are used in between then is there any way to handle them just like reactors.
Thanks & Regards,
