I added a Border with a custom line style to a Figure. The result was that
painting of guide lines got completely messed up.
It's easy to reproduce even with the Logic example:
a) Modify LEDFigure (or any other Figure) constructor and add the following
code:
setBorder(new LineBorder() {
public void paint(IFigure figure, Graphics graphics, Insets insets)
{
//Save state
graphics.pushState();
int lineStyle = graphics.getLineStyle();
graphics.setLineStyle(SWT.LINE_CUSTOM);
graphics.setLineDash(new int[]{16,8});
super.paint(figure,graphics,insets);
graphics.setLineDash(null);
graphics.setLineStyle(lineStyle);
//Restore the state
graphics.popState();
}
});
b) Run the example, and open an existing or create a new Logic diagram.
c) Turn on the ruler display. Create a few guides.
d) Add the LED figure to the diagram.
e) Drag it around, crossing the guide lines.
f) See the guide lines appearing and disappearing randomly.
g) When drag is completed, all guide lines disappear which were touched or
crossed during the drag.
Note that the custom paint method restored the graphics state when it
completed.
Randy/Pratik: Any idea what's going on? Should I just go ahead and file a
report in Bugzilla?

OK, I will vote for it, if that helps.
