So i have a graphics layer (gLayer)

when i draw a polygon onto graphics layer, it works ok
when i then select to draw a second, the first point i draw i get the following error

RangeError: Error #2006: The supplied index is out of bounds.

Steven,

this sample code works perfectly.

Can you show your code?
