preferredSize problem [message #193632]

I'm having a problem with the Figure#preferredSize() call. I want figureA
to snap to the side of figureB. When figureA is first created I set
figureA.x = figureB.x - figureA.width. FigureA's width is set to the
figure's preferred size but still always leaves a small gap. On subsequent
calls the width of figureA is smaller and then snaps perfectly, it is the
propper size. So I was wondering how to calculate the proper preferredSize
before the figure is displayed.

I have a layout manager that calculates my figure's preferred size. In
GraphicalEditor#initializeGraphicalViewer() I calculate and set the size of
every model node. Since setting the models's size triggers a refresh,
everything looks fine right away.
