[OpenLayers-Users] BBOX Strategy and StyleMap problem

[Arnd Wippermann]

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

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
