<pre wrap="">Hello Jan,
I think you have the same problem as my. Just add "<span class="156232221-08032012"><font color="#0000ff" face="Arial" size="2">resFactor to the BBOX.Strategy</font></span>"<span class="734173216-09032012"></span>.
<a class="moz-txt-link-freetext" href="http://dev.openlayers.org/docs/files/OpenLayers/Strategy/BBOX-js.html#OpenLayers.Strategy.BBOX.resFactor">http://dev.openlayers.org/docs/files/OpenLayers/Strategy/BBOX-js.html#OpenLayers.Strategy.BBOX.resFactor</a>
Try using something like:
new OpenLayers.Layer.Vector("Punkte", {
strategies: [new OpenLayers.Strategy.BBOX({resFactor:1})],
protocol: new OpenLayers.Protocol.HTTP({
url: "text_layer_generator/points.php",
format: new OpenLayers.Format.Text({
extractStyles:false
})
})
});
</pre>
I hope it helps.<br>

Layer.Markers.redraw(), but thet didn't solve the problem: the
markers only moved to their new position,when their lonlats had
been changed, after an addition zoomin or zoomout. In your map
the markers always remain on the same spot.<br>

<pre wrap="">Well, first removing and then adding all markers from the markers layer
will force the update. Not elegant, but it works.

<pre wrap="">Hi,
How do I force a redraw on a markers layer? I have a regular WMS map
with markers that have their lonlat-values updated from a database. I
can force a redraw of the WMS layer with mergenewparams(), but that is
not possible with the markers layer. That means that the when the
lonlat values are updated and I move the map, the markers remain in
their original positions. Only when I zoom in or out, the marker
positions are updated. Can I do something about that?

<pre wrap="">What about calling layer.redraw();
For my weather site I had to solve the same problem. The solution was
calling the redraw methode of the markers layer.
