[OpenLayers-Users] Different icons for popups

[bzrudi]

Hi list!

I have a strange problem with applying different icons to my 
markers/popups using addUniqueValueRules(). I see all the examples and 
read a lot but unfortunately it doesn't work as expected, so one may 
help me out here please ;-)

So what I did. Defined a styleMap as below and bind my Vectorlayer to it.

var markerStyle = new OpenLayers.StyleMap({
	externalGraphic: '../museum.png',
         fillOpacity: 1,
         pointRadius: 10,
});

vectorlayer = new OpenLayers.Layer.Vector('Infos', 
     	{displayInLayerSwitcher: true,
	styleMap: markerStyle});

This works as expected, all my markers have the "museum" icon instead of 
the circle/point. I now tried to apply differnt icons to the 
markers/popups using this as example:

var lookup = {
	attraction: {externalGraphic: '../attraction.png', pointRadius: 15, 
             $js .= "vectorlayer = new OpenLayers.Layer.Vector('Polygon 
Layer',
                                 {displayInLayerSwitcher: true,
                                  styleMap: markerStyle});\n"; 
fillOpacity: 1},
         museum: {externalGraphic: '../museum.png'}, pointRadius: 15, 
fillOpacity: 1},
}

and also add:

markerStyle.addUniqueValueRules("default", "attraction", lookup);

Now, instead of having all my markers using the "attraction" icon (what 
is what I expected) - the markers are no longer displayed.
I tried lots of things to get rid of this but have no more idea how to.
Unfortunately I'm a PHP programmer with just basic JS knowledge. So if 
there is anyone who can help, please let me know, thanks!
