[OpenLayers-Users] Adding a new feature with different graphics

[Pierre GIRAUD]

If I'm correct, what you want is to be able to distinguish vector
features by their state eg. update, insert, delete, unknown. The
vector features drawn by user and not yet committed to server would be
of insert state.

Currently, there's already a "state" property for the Vector.Feature
class object.

What you need is :
 - to set that state to "OpenLayers.State.INSERT" when the user draws
a new feature, you can easily do this with events at the layer's level
[1]
 - to have different styles for the different states. [2]

Pierre
