Hi Brice,

I think you should use MindMapFactory.eINSTANCE.createTopic();
And then you need a AbstractTransactionalCommand to add the Topic 
persistent to the Map. At the place where I put <thisMap> you have to 
find the Map, which contains all Topics, Relations etc. This depends on 
where you create the Topic.

Topic newTopic = (Topic)MindMapFactory.eINSTANCE.createTopic();
TransactionalEditingDomain editingDomain = 
((MindmapDiagramEditor)getPart()).getEditingDomain();
AbstractTransactionalCommand cmd = new 
AbstractTransactionalCommand(editingDomain, "create topic", null, null)
{
	@Override
	protected CommandResult doExecuteWithResult(IProgressMonitor monitor, 
IAdaptable info) throws ExecutionException
	{
		<thisMap>.getRootTopics().add(newTopic);
		return CommandResult.newOKCommandResult();
	}
};
				
try
{
	OperationHistoryFactory.getOperationHistory().execute(cmd, new 
NullProgressMonitor(), null);
}
catch (Throwable t)
{
	System.err.println(t.toString());
}

I think this should work.
Best wishes
Julia
