[news.eclipse.modeling.amalgam] DSL Book - problems with java code pg 81

[dave1@xxxxxxxxxxxxxxxx (Dave Milham)]

I am steadily working my way through the DSL Toolkit book and have got to 
a point on pg 81 where I need a clue as to what to do next
I am using the Amalgam downloaded DSL toolkit and JAVA 6. 

I have made the changes to the constructor Public TopicFigure() - middle 
page 81 and also to createContents() - top page 82 and the java editor 
flags errors.

I searched the examples and I think th correct code  is in:

http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.gmf/examples/org.eclipse.gmf.examples.mindmap.diagram/src/org/eclipse/gmf/examples/mindmap/diagram/edit/parts/TopicEditPart.java?root=Modeling_Project&view=markup

However this look quite different from the book.
The specifc erro I get with the code in the book is that the parser cannot 
resolve the name Rectangle and the import 
import java.util.List;

marks Rectangle as not used.

I can partially resolve the porblme by using a full name like 

I can resolve some of the errors by using the full path name 
org.eclipse.draw2d.geometry.Rectangle but get error with Child.
Looking at the import I see that it has markers that some imports are not 
used such as 
import org.eclipse.swt.graphics.Rectangle

however using this path name does not resolve the errors

What would be useful is
1. confirmation that the code on Pg 81 and 82 works 
2. that the URL for the example code above is the correct one and if not 
where the correct code can be found.


many thanks
