Maybe I found something.
Diagram diagram = ViewService.createDiagram(model, MethodContentEditPart.MODEL_ID, MethodContentDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
try {
for(Task task : model.getTasks())
{
Node node = ViewService.createNode(diagram, task, MethodContentElementTypes.Task_2003.getId(), MethodContentDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT);
...
It should create the node into my diagram, but nothing is happen.
So I tried to insert it on diagram using this:
diagram.insertChild(node);
But when I do it, it throws this exception
java.lang.IllegalArgumentException: The 'no null' constraint is violated
