[OpenLayers-Dev] Editable polygon

[Andy Deakin]

This is great! Thanks.

Is there a preferred way to find the coordinates of an edited polygon 
(e.g. to send back to a server via ajax).
At the moment I have found two ways:

1) Parsing the polygon.geometry.toString() by stripping off the 
POLYGON(( and )), then splitting by comma, then splitting by space 
(seems a bit messy)
2) loop through polygon.geometry.components[0].components[i]

In the documentation 
http://dev.openlayers.org/docs/files/OpenLayers/Geometry-js.html there 
also appears to be a getVertices() function, but it doesn't seem to 
exist. Has this been removed?

Also, it there the feature to transform the coords into decimal degrees 
format on the client side?

Thanks again
