| How to get the parent of an EAttribute ?? [message #410299] |

Hello,
I have the following model
<DocumentRoot>
<Ident>
<ID>123</ID>
<Anot>A1</Anot>
<Anot>A2</Anot>
<Anot>A3</Anot>
</Ident>
</DocumentRoot>
The IdentType has two attributes, ID and Anot. Anot returns an EList of strings.
Now if i do EObject eObject = this.identType; and then
System.out.println(eObject), i get the JobIdentImpl with all the content and values.
Now, in one of my methods, i iterate within the JobIdent and try to get the parent of Anot via:
EObject parent = eAttribute.eContainer();
and then try to print parent, i only get the following:
org.eclipse.emf.ecore.impl.EClassImpl@1c10834 (name: JobIdentificationType)....
This causes problem for me since i cannot get the values of Annot via:
Object value = parent.eGet(eAttribute);
any suggestions?
Thanks.

This is asking the parent of the meta data object, which will be another
meta data object and will have nothing to do with your particular instance.

There is no EObject representing the Anot element (unless it was an
element that had a complex type with simple content rather than an
element with a simple type). So this is like wanting to know the parent
of a java.lang.String. A String don't know who is all referencing it,
and, in general, the value of an EAttribute will not know that it's
being referenced by one or more EObjects.
