Hi,
I'd like to store up the location/size information some where other than
the business model. All the GEF examples store such information in the
model elements for resize and move notification. Do I have other
alternative ? What is the best practise ?
Thanks for any information.

Hello,
I have pondered the issue myself for quite a while, because I did not
like the idea of putting display-specific infrastructure into my model
classes.
My conclusion is that if you really want (or have to) keep your model
clean, the only way is to introduce an intermediary model layer between
the editparts and the model proper. Here you can add location and other
display info - which you may want to store permanently later - and
property change support etc.
The EditParts themselves are not well suited for this, as you may not
have them handy when you need the data (e.g., storing or reading from file).
hth, chris
