[udig-devel] feature editing

[Jesse Eichar]

I have added detection during editing so you are notified when the  
data you are editing changes.  Unfortunately the event model is  
really bad and I am having difficulty determining whether or not the  
change requires an update to the geometry or not.  Take this as an  
example.  Suppose you are editing a polygon and some one else  
modifies that polygon.  You want to know that the polygon has changed  
so that you can decide to ignore the change and overwrite it, or  
cancel you changes, get the update and restart you editing.

Well the problem comes that the event system is VERY basic and I  
can't tell what changes are occurring from external sources and what  
are from the current source.  I also can't determine if the geometry  
has been modified or if attributes have been modified.  I will make  
changes so that it is less obtrusive for the time being until I can  
improve slightly on the events.
