Using keyword 'super' in GenModel annotation [message #422737]

Hello

I noticed some strange behavior in the ecore code generation.

I have a ecore model and try to override the toString method using the
'http://www.eclipse.org/emf/2002/GenModel' annotation.
This works if I add a 'body' part like <% return super.getName(); %>

If I add <% return super.toString(); %> my generated class gets
messed up.

Here the ecore part:
<eOperations eType="ecore:EDataType
http://www.eclipse.org/emf/2002/Ecore#//EString" name="toString">
<eAnnotations source="http://www.eclipse.org/emf/2002/GenModel">
<details key="body" value="<% return super.toString(); %>"/>
</eAnnotations>
</eOperations>

And here my class:

package ch.scodi.model.model.impl;

import return super.toString(); ;

import ch.scodi.model.basic.impl.RoleBasicImpl;

import ch.scodi.model.model.ModelPackage;
import ch.scodi.model.model.Role;

import org.eclipse.emf.ecore.EClass;

/**
* 
* An implementation of the model object 'Role'.
* 
* 
* 
*
* @generated
*/
public class RoleImpl extends RoleBasicImpl implements Role
{
/**
* 
* 
* @generated
*/
protected RoleImpl()
{
super();
}

/**
* 
* 
* @generated
*/
protected EClass eStaticClass()
{
return ModelPackage.Literals.ROLE;
}

/**
* 
* 
* @generated
*/
public String toString()
{
toString();
}

} //RoleImpl

Now notice the first import statement??? Also the toString method is
missing the 'super' part.

Am I doing something wrong or is this a EMF Bug? Is super somehow used to
add additional imports?

The <%%> is supposed to surround just the fully qualified name that you
want imported. In this case you don't need any such brackets.

Since your snippet contains no fully qualified class names, you
shouldn't use <%...%>

Thanks Ed, got it to work! I misunderstood the EMF Book.
