Hello

I have a problem.
I create in a CreateFeature (extends from AbstractCreateFeaturea) a vertex (in the create method) and I want to create ports in a static way with them.

...
Vertex vertex = ...
addGraphicalRepresentation(context, vertex);


The problem is at this point.

Port port = ...
addGraphicalRepresentation(context, port);


The context.getTargetContainer() is a instance of Diagram but I need a instance of something which has somting to do with the vertex.
So I have to create a new context which has somting to do with the vertex, but I don't know how to do.

Probably you would simply need to create a new AddContext like this:
AddContext addBookContext = new AddContext(new AreaContext(), <domain
object to add>);
addBookContext.setTargetContainer(<the container shape in which to add
the object representation>);

Hello

I have a problem with this one

addBookContext.setTargetContainer(<the container shape in which to add 
the object representation>);


How do I get
<the container shape in which to add the object representation>

The only thing I have is:
PictogramElement v = addGraphicalRepresentation(context, vertex);


And I don't know how I get the right container shape.

This one I tried causes a NullPointerExceptions:
IPeCreateService peCreateService = Graphiti.getPeCreateService();
        ContainerShape contShape = peCreateService.createContainerShape(context.getTargetContainer(),false);
        
        
addBookContext.setTargetContainer(contShape);

I add somthing
PictogramElement vertexPE = addGraphicalRepresentation(context, vertex);
...
//I add this
contShape.setGraphicsAlgorithm(vertexPE.getGraphicsAlgorithm());


however the NullPointerException happens now after the return.
I write the exception too(I don't thing it is helpful)

Hauke,

I hope that I understood the issue behind now: it seems that you exspect the
method call to addGraphicalRepresentation to do the adding of the visual
representation to the diagram? But this is not what the method does, it
simply delegates to the feature provider to find a suitable feature that is
capable of adding the stuff to the diagram.

What you would need to in your add feature do instead is create the
graphical representation by yourself (e.g. using the create methods from
PEService and GAService). The method addGraphicalRepresentation is only
meant fo adding sub objects that are handled by their own add feature...

For an example have a look into the TutorialAddEClassFeature.
