[Pharo-dev] RTPolygon does not work ?

Hi, does anyone know how to use RTPolygon shape or is there a real problem inside ? For exemple you get an error when executing: -=-=-=-=-=-=-=-=-=-=-=-= v := RTView new. p := RTPolygon new vertices:{ 25 @ 00 . 10 @ 50 . 50 @ 20 }. v add: (p elementOn: 1). v open -=-=-=-=-=-=-=-=-=-=-=-= Apparently the instance variable "strokePaint" of TRShape class, would be Nil when used by TRPolygonShape... But this variable seemed to be initialized in color black earlier so... I don't know what's appenning. If someone have a Idea... Thank you, PIerre
