Re: [Openjgraph-development] Setting text displayed on a VisualEdge

Although the actual String has been changed, it has never been rendered. 

As soon as an Edge is added to the Graph, and it has a corresponding 
VisualGraph, the VisualGraph is told to repaint() itself so that the new 
VisualEdge is drawn. Your setText() is called after the repaint() of the 
VisualGraph. So you need to call repaint() again.
