Hi Mario,
I don't no why, but for the KML-Layer the
propertyStyles:{externalGraphic:true} have to be set.
For the Text-Layer it isn't needed.
I have updated my example to show the difference between the two formats.
Regard,
Arnd

Betreff: Re: [OpenLayers-Users] BBOX Strategy and StyleMap problem
Dear Arnd,
it should but it doesn't work.
I don't know why...
I implemented a work-around with an ajax call into the moveend event linked
to the map
eventListeners: {
"moveend": mapEventMove,
}
In "done" ajax case i parsed the text results and used the removeAllFeatures
and addFeatures.
Thanks
Mario Danelli
