[OpenLayers-Users] WFS layer, markers and popups

[Marcos Nogueira]

Hi everyone,
I am developing an application wich has WFS Layers.For one layer, I was
using featureClass: OpenLayers.Feature.WFS and so I get the red marker in
the points, but for
the other layer I use:

 var symbolizer = OpenLayers.Util.applyDefaults(
           {externalGraphic: "img/marker-blue.png", pointRadius: 10}

           var especimeA = new OpenLayers.Layer.WFS("especime A",
            "http://127.0.0.1:8081/cgi-bin/mapserv.exe?map=c
:\\maps\\teste_postgis.map",
            {typename: "zctas"},
            {styleMap: new OpenLayers.StyleMap({
                                   "default": symbolizer})
                           });
            map.addLayer(especimeA);


For that layer in which I use the blue marker, as I move the map, the
markers move their position too.  If I change it to
 featureClass: OpenLayers.Feature.WFS, the points stay where they should be
if I move the map or not.
My base layer is a google maps one.
My questions are:

1 - Why is it happening and how do I fix it ??

2 - How can I associate a popup to each point ? and how can I render
information that is in my DB (postgis) in it ?

For example, I have:
id   Name  Point
1    Cat     (-23,-45)
I'd like to associate a popup in it so that it shows "Cat" for example when
I click in the marker representing the point (-23,-45) in the map.

I am using Mapsever (MS4W), postgre 8.3, postgis 1.3.6 and openlayers 2.8

Thanks for your attention guys,

Marcos
