[OpenLayers-Users] BBOX Strategy and StyleMap problem

[Mario Danelli]

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
