[OpenLayers-Users] How to use split events

[Andreas Hocevar]

Hi,

instead of working with the split event, use a beforesplit event handler
and check the geometry of the target feature. Return false from the
beforesplit handler if the target feature has more than 1 part (note:
before splitting!).

Regards,
Andreas.
