[OpenLayers-Users] GML and KML styleMap

Tue Feb 17 08:37:32 EST 2009

Yes,
I am using v. 2.7 but it's  like the extractStyles attribute  behaves
correctly.

I've come to the real problem in my code: it seems like feature attributes
are not loaded from the KML file (and extractAttributes is set to true).
(I'm debugging with firebug)
This causes visualization problem as I set a "loadend" event which modifies
the styleMap adding a rule based on one of the attributes. This works
perfectly with the GML format.

here is an excerpt of my KML file (with only 1 feature in this case):

<?xml version="1.0" encoding="utf-8" ?>
