Re: [Geoserver-users] GE styles change

[Chris H. <ch...@op...>]

Actually, thinking on it, it may be possible that adding a LineStyle to 
the KML Style output will make it properly render, as I could see them 
having that sort of logic in google earth.

Travis, could you possible take some KML output and add in a LineStyle, 
in addition to the PointStyle and PolyStyle that we set for polygon 
output, set the width to something large, and see if google earth 
renders it different?

If so then we will know that it'll work, and then put an issue in to our 
task tracker - http://jira.codehaus.org/browse/GEOS and we'll get it 
fixed for you.

best regards,

Chris
