| Diagram root element [message #138381] |

Hi all,
is have the following case - after the diagram generation i got among all
classes one that do not compile - xx.diagram.part.xxDiagramEditorPart.java
The cause is the following method:
private static DocumentRoot createDocumentRoot(DocumentRoot model) {
DocumentRoot docRoot = ScaFactory.eINSTANCE.createDocumentRoot();
docRoot.setDocumentRoot(model); // FIXME name of the set method is pure
guess
return docRoot;
}
FIXME is also generated, and DocumentRoot has for sure no setter method
for DocumentRoot itself...
I wrote in the dev group, assuming this is a bug, but got the reply, that
I should not use DocumentRoot as diagram root element, but some model
element.
The question is - what should I do now - the DocumentRoot seems as a model
element (appears in the .ecore model as element) and is the only object
that contains the elements I wish to display in the diagram? The model can
not be modified - it is generated form public XSDs...
Best regards,
Krasi

Hi Krassimir,
I work also on SCA. I'm developing a designer to define assemblies and
like you I also modified the createDocumentRoot method.
However, I have another problem. This problem appears with elements
which include a substitution group attribute.
The generation of the ecore model is correct. Any element declaration
that is the head of a substitution group produces a feature map in the
Eclass corresponding to any referencing elements. In addition to the
normal EReference in the corresponding EClass, a feature map EAttribute
is created. The name of the FeatureMap EAttribute is the same as the
name of the element's corresponding EReference with the string "group"
appended. The element's corresponding Ereference is derived from the
FeatureMap... Everything is all right.
When I use the EMF editor everything is ok. But when I use my GMF editor
I can't add elements of this type. For example, I can add a
JavaImplementation (the head of the substitution group is
Implementation) to a Component in the EMF editor but I can't do it in
the GMF editor. The following exception is launched:

I changed the property of the "implementation" attribute to modifiable
but XML documents are serialized using xsi:type attributes... I know
that this is not the good solution ;)
Do you know this problem? Do you have any idea of how to solve it?
Thank you and best regards.
