O.K.  I added the code to be able to add polygons to the example... It 
created the following output...

<wfs:FeatureCollection 
xmlns:wfs="http://www.opengis.net/wfs"><gml:featureMember 
xmlns:gml="http://www.opengis.net/gml"><feature:features 
xmlns:feature="http://mapserver.gis.umn.edu/mapserver" 
fid="OpenLayers.Feature.Vector_199"><feature:geometry><gml:Polygon><gml:outerBoundaryIs><gml:LinearRing><gml:coordinates 
decimal="." cs="," ts=" ">11.6015625,0.703125 29.70703125,0.87890625 
29.53125,-7.734375 12.12890625,-7.734375 
11.6015625,0.703125</gml:coordinates></gml:LinearRing></gml:outerBoundaryIs></gml:Polygon></feature:geometry><feature:name>ddddddd</feature:name></feature:features></gml:featureMember><gml:featureMember

It came out of this code...
        function serialize(feature) {
            feature.attributes = {};
            var name = prompt("Name for feature?");
            feature.attributes['name'] = name;
            var data = g.write(feature.layer.features);
            OpenLayers.Util.getElement("gml").value = data;
            trace.innerHTML=feature.layer.features;
        }

The last line I added only generates [object Object],[object Object].  I 
was looking for g.write and can't find that to see what it is looking at 
to generate the data in the variable "data".

How do I use this in order to save and put these polygons back into the 
polygon layer???  Honestly, I don't know what this object is that I'm 
looking at.  My goal is to dynamically generate the polygon from other 
code I've already written and insert it into the polygon layer.  Then 
when the cursor is hovered over the polygon, I can display data 
associated with the polygon.

Thanks,
