Now if i click on service it opens a class with the Methods public ProrPresentationConfiguration getConfigurationInstance() and public Class<? extends ProrPresentationConfiguration> getConfigurationInterface(). Are these the Methods getCellEditor() and getCellRenderer(), which are needed in the Guide?

I click on service in the Extension view and then following class is created

And with the AbstractPresentationService i don't need the getCallEditor and getCallRenderer methods, the getConfigurationInstance Method is enough?

I wanted to know if one of these is the new Presentation.

And i wanted to know if the HeadlineConfigurationItemProvider was the right class to implement the PresentationEditorInterface.

Can this be done with the Presentation or what is the best way to handle this?

is it enough to change the name in the ecore Modell? In the Properties-View of Headline.ecore.

I would be nice if someone could explain, how the Parameters are used and for what they are needed.

	 * The cell editor must use EMF commands to set the new value.  That's the reason why the other
	 * parameters are provided.  Briefly, the easiest is to do the setting via 
	 * {@link ProrUtil#setTheValue(AttributeValue, Object, Object, Object, EditingDomain)}, which
	 * allows you to just and the parameters through.

In the getCellEditor Method I call setTheValue with the parameters needt for the getCellEditor Method.

return new LinewrapCellEditor(agileGrid, editingDomain, parent,
    affectedObject);

protected Object doGetValue() {
    String newText = (String) super.doGetValue();
    ProrUtil.setTheValue(attributeValue, text.getText(), parent,
        affectedObject, editingDomain);
    return attributeValue;
}

Then what are EditingDomain, parent, Object value and AgileGrid?

I would like to know, how i can achive following task:
I want to set the Enumeration Field with SpecObject identifier
rmf-17d2cd15-8cfd-4cdo-a339-16789998bef7 to true
What do I use as parameters to call
getCellEditor(AgileGrid agileGrid, EditingDomain editingDomain, AttributeValue av, SpecElementWithAttributes parent, Object affectedObject)?

AddCommand.create(editngDomain, parent, ReqIF10Package.Literals.ATTRIBUTE_VALUE_ENUMERATION__VALUES, enumValue);

Hello, to call the Cell I need the Idetifier of the Spec Object, not of the Spec Hierarchy?

Do I write the Identifier with or without the " - "?
