Hi,
Finally I added the 1700 features like this:
....
featuresAll.push(new OpenLayers.Feature.Vector(new
OpenLayers.Geometry.Point(<bean:write name="item" property="lon"/>, <bean:write
name="item" property="lat"/>),
{ id: asdf,
lat: asdf,
lon: asdf,
confidence: asdf
} ) );
...
allDetections.addFeatures(featuresAll);
Is it normal that the web browser does not let me load the layer? it says that
a javascript script is taking a lot of time, and I need to stop it, but after 5
minutes the layers is loaded. Features layers are usually used for a lower
number of features??
Thanks

Hi,
you may want to have a look at the new Filter strategy:
http://dev.openlayers.org/releases/OpenLayers-2.10/doc/apidocs/files/OpenLayers/Strategy/Filter-js.html
This requires OpenLayers >= 2.10.
Regards,
Andreas.
