I`ve a GaphicalEditorWithPalette and just have implemented the zoom
feature from logic example. But when i open a saved editor the initial
zoom level is somehow set to 50%.
Why does it not open to 100% ?

The setting is saved in the document, just like in Word or other
applications.

I see...
When i tested it in the logic example i didn`t save the model, just =

changed the zoom without moving anything.

OK. I have set a break point on doSave and have completely traced the sa=
ve =

progress in my editor.
The problem is that intitially the zoom value of the Diagram is 0.0 =

instead of 1.0. I have no idea why...
The declaration in Diagram model class: private double zoom =3D 1.0;

....so it should be 1.0!!!

As 0.0 is no allowed zoom the zoom level is set to its smallest size or =
=

first entry in zoomlevels.

But why how can this be? it is set to 1.0 in it`s declaration!

Maybe it is a serialization (compatibility) problem. Zoom field was added
in 2.1. If you try to saturate an older model which didn't have that field,
maybe it gets read in as 0??
