No labels after using IFigureProvider [message #786108]

I implemented IFigureProvider in my LabelProvider and I return the Ellipse() figure for my nodes. The custom figure displays perfectly but my labels (returned by getText(...)) do not show up anymore for my nodes (they do show up for my connections).
Is there a way to get my labels to show up again?

I figured out that the IFigure has to draw the label itself. So in my IFigure getFigure(Object element) method I now create a custom Figure derived from Ellipse that adds a label to itself. It uses a StackLayout to have the label on top of the ellipse. Something like this (constructor of custom Figure):

super();
this.setForegroundColor(ColorConstants.black);
this.setBorder(new MarginBorder(4));
this.setLayoutManager(new StackLayout());
((Shape) this).setLineWidth(1);
((Shape) this).setAntialias(1);
mLabel = new Label(text);
mLabel.setForegroundColor(ColorConstants.black);
mLabel.setFont(Display.getCurrent().getActiveShell().getFont());
this.add(mLabel);
