Hi Stephen
Here is some code I use. I load the WFS layer as a GML, and make sure that
extractAttributes is set to True on load:
var apigml = new OpenLayers.Layer.GML("Selected Apiary",
"http://10.65.192.1/cgi-bin/apimgwfs.exe?apiaryid="+apiaryid+"&request=getfeature&typename=apiaries&service=wfs&version=1.0.0&BBOX="+x1+","+y1+","+x2+","+y2
(
'http://10.65.192.1/cgi-bin/apimgwfs.exe?apiaryid="+apiaryid+"&request=getfeature&typename=apiaries&service=wfs&version=1.0.0&BBOX="+x1+","+y1+","+x2+","+y2'
),
{styleMap: myStyles, extractAttributes: true});
map.addLayer(apigml);
var options = {
hover: true,
onSelect: function(feature) {
OpenLayers.Util.getElement('apiary').innerHTML =
"<strong>Apiary_id:</strong>" + feature.attributes.apiary_id + "
<strong>Beekeeper_reg_no:</strong>" + feature.attributes.beekeeper_reg_no + "
<strong>MAF_id:</strong>" + feature.attributes.maf_id
Cheers,
Robert Sanson }

Hi all,
I'm making progress but can't find the attributes of the WFS features.
My goal is to load a WFS layer, pull the attributes into a div as a
scrolling list of items and when you mouse over the item in the
scrolling list have it highlight the feature on the map.
To start with, I'm approaching this backwards and just displaying the
WFS and highlighting the features onHover over the map, with the idea
that if I can grab the attributes and make a list, I can add onHover
handler to the list items and have them select the feature. Any way that
was my thought, but maybe there is a better way to do this.
I assume I can hook the beforefeatureadded or featureadded to extract
the attributes and add them to the list in some div, assuming that I
have access to the attributes which is a problem at the moment.
Thoughts and pointers to examples would be appreciated.
Anyway, missing attributes - the attributes are in the XML, but do not
appear to be added to the features objects at least as far as I can tell
but looking in the DOM with firebug. And adding to the selectFeature
control:
onSelect: function (feature) {
alert(feature.attributes["gid"]);
}
returns a undefined. Here is a link to the page:

Once it loads and displays the vector layer, a hover will generate an alert.
Thanks,
-Steve
