Cell Change Event in Libreoffice gets called twice

I am trying to use XModifyListener class to listen to cell change Events for LibreOffice Calc.My problem is :: When a user modifies a cell, the event is getting triggered twice.public void modified(EventObject event) is getting called twice in my code.I have to perform custom tasks in a cell change event and I end up doing it twice which is leading to errors for me.
Can you please help me to solve this issue.
PS: Registering for the events is done only once. I have cross verified this and this is not an issue. xModifyBroadcaster.addModifyListener(xModifyListener) - the code to register for the change event is called only once and hence no issues there.

Post your code.

The solution was to use XModifyBroadcaster with the cellRange rather than the whole document.
