Hi.
I have a question about adding s child reference to a basic class.
My Model:
Expression (abstract), Plus (extends Expression), Minus (extends
Expression and so on)…
Body hasMany Expression, Declaration has Expression, Function has Body and
hasMany Declaration.
Graphics:
I have a figure for each type of expression.
I want to realize editor that will allow me to create a body and add some
expression to it (Plus, Minus and so on) and will allow me to create a
declaration and add an expression to it. What should I write in my gmfmap
file? I created a node mapping for function. I created a child reference
with node mapping for Declaration in function node. All works fine. Now I
want to create a child reference that will allow me to add any expression
to this declaration. But if I add a child reference I can’t select
a containment feature. How can I do it?
Best Regards, Savkin Viktor.

It seems like you got the same problem as I got.
The editor is able to place
'red round', 'green rectangle' and 'green round' shapes
on the canvas (called 'GesamtMenge')
I build this first:
=======================================
<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" name="mengenlehre"
nsURI="mengenlehre" nsPrefix="mengenlehre">
<eClassifiers xsi:type="ecore:EClass" name="RotRund"/>
<eClassifiers xsi:type="ecore:EClass" name="GesamtMenge">
<eStructuralFeatures xsi:type="ecore:EReference" name="gRotRunde"
upperBound="-1"
eType="#//RotRund" containment="true"/>
<eStructuralFeatures xsi:type="ecore:EReference"
name="gGruenRechteckige" upperBound="-1"
eType="#//GruenRechteckig" containment="true"/>
<eStructuralFeatures xsi:type="ecore:EReference" name="gGruenRund"
upperBound="-1"
eType="#//GruenRund" containment="true"/>
</eClassifiers>
<eClassifiers xsi:type="ecore:EClass" name="GruenRechteckig"
eSuperTypes="#//Gruen"/>
<eClassifiers xsi:type="ecore:EClass" name="Gruen" abstract="true"/>
<eClassifiers xsi:type="ecore:EClass" name="GruenRund"
eSuperTypes="#//Gruen"/>
</ecore:EPackage>
I did the whole wizard stuff and got a working GMF edit. (BTW: Great thing!)
The second version doesn't work. The difference is that the
the canvas (GesamtMenge) has a reference list to the abstract class
(Gruen)
instead of each derived concred classes GruenRechteckig and GruenRund.
It would be easier to handle it that way.
