Hi,

I'm trying to create the view of an existing semantic element created in program, already added to model; to do so I found this way:

private Command createViewCommand(EObject template) {
CreateViewRequest.ViewDescriptor viewDescriptor = new CreateViewRequest.ViewDescriptor(new EObjectAdapter(
template), Node.class, ((IHintedType) XXXElementTypes
.getElementType(XXXEditPart.VISUAL_ID)).getSemanticHint(), true, CanvasEditPart
.getDiagramPreferencesHint());
viewDescriptor.setPersisted(true);
CreateViewRequest createViewRequest = new CreateViewRequest(viewDescriptor);
Command createViewCommand = CanvasEditPart.getCommand(createViewRequest);
return createViewCommand;
}

How can I translate the code
((IHintedType) XXXElementTypes
.getElementType(XXXEditPart.VISUAL_ID)).getSemanticHint()
for the type Port?

Thanks in advance, 123star

VISUAL ID: org.eclipse.papyrus.diagram.composite.edit.parts.PortEditPar t.VISUAL_ID
Element types: org.eclipse.papyrus.diagram.composite.providers.UMLElementTy pes

Cheers

Thank you Remi,

I've put in the code, but this exception occurs when I call the method for creating the view of the port:

Caused by: org.eclipse.core.runtime.AssertionFailedException: null argument:failed to create a view
at org.eclipse.core.runtime.Assert.isNotNull(Assert.java:85)
at org.eclipse.gmf.runtime.diagram.ui.commands.CreateCommand.do ExecuteWithResult(CreateCommand.java:99)

at org.eclipse.gmf.runtime.diagram.ui.commands.ICommandProxy.ex ecute(ICommandProxy.java:68)
at org.eclipse.gef.commands.CompoundCommand.execute(CompoundCom mand.java:111)

I tried different ways to do this, but I always get this exception.
I miss something, I looked through GMF forum, but I didn't find some working code.
For now I haven't managed to find a way to synchronize the view with the model...

Thanks in advance, 123star

It seems that the framework can not create the view.

Have you try to create the view element with the good parentview.

For exemple the parent view of the port can be a class view not a compartment.
What is your variable "template".

I have the same problem as you. Did you resolve this problem?
I wish to create a view of an existing semantic element created in program.
I used your code and I have the same exception.

Thank you in adavance!!
