Description
Occasionally but rarely get a VisADSetException when drawing ONOs. 99% of the time there's no such exception. Double check math; if it seems okay, try to reproduce the error (maybe using an automated test).

Replying to sorber:

The title of this bug should read (OverlayUtil).getSelectionLayer(), not getData()

OverlayUtil.getNodedLayer() no longer tries to create a Gridded2DSet for pairs of colocational nodes.

- Status changed from new to closed
- Resolution set to fixed
One reason this occurs: the OverlayObject.isDrawing flag is false when the user resumes drawing an existing polyline, so OverlayTransform tries to draw a grid. Each time the user places a node, the last two nodes are briefly overlapping, resulting in an invalid grid. To solve: go through polyline tool and add setDrawing() calls where appropriate.
