[Matt Priour]

this line
featureNS: "topp" 
        OR 
        "http://www.openplans.org/topp"
you need to use one or the other. so it should be either
featureNS:"topp"

or

featureNS:http://www.openplans.org/topp

but not both in the same place like that.

Thank you very much, I wrote my remain problem here, I hope you can help me one more time 




I am trying to do as this example http://ian01.geog.psu.edu/geoserver/www/search/gazetteer.html  
for searching by using WFS as example functions bellow: 

 var protocol= OpenLayers.Protocol.WFS({        url: "http://ian01.geog.psu.edu/geoserver/wfs",        featureType: "pop_places",        featureNS: "http://geovista.psu.edu"    });    formPanel = new GeoExt.form.FormPanel({        title: "Place Name Search",        height: 150,        region: "north",        protocol: protocol,        items: [{         
   xtype: "textfield",            width: 200,            name: "name__like",            //value: "State College",            fieldLabel: "name <br />(use * and . for wildcards)",            allowBlank: false,            minLength: 4,        }],        listeners: {            actioncomplete: function(form, action) {                features = action.response.features;                store.loadData(features);                vm=map.getLayersByName("Results");                if(vm.length===0){                    vecLayer = new OpenLayers.Layer.Vector("Results");                    map.addLayer(vecLayer);                    store.bind(vecLayer);                    select.bind(vecLayer);                }            }        },        buttons: [{text: 'search',            handler: function(){                formPanel.search();            }        }],    
    keys: [{ key: [Ext.EventObject.ENTER],             handler: function() {                formPanel.search();            }        }]    });when I use FireBug for checking GET method in console is showed GET http://ian01.geog.psu.edu/geoserver/wfs==>In my case, I change above code for exactly my cases as bellow:



var protocol= OpenLayers.Protocol.WFS({        url: "http://localhost:8080/geoserver/wfs",        featureType: "municipalities",        featureNS: "topp"         OR         "http://www.openplans.org/topp"    });formPanel = new GeoExt.form.FormPanel({        title: " Search",        height: 150,        region: "north",        protocol: protocol,        items: [{            xtype: "textfield",            name: "name__like",            fieldLabel: "Population=",        },        {                  xtype: 'textfield',                  fieldLabel: '  Population  >',                  name: 'POPULATION__ge'				               }],        listeners: {....same above exampleothers functions are configured all most same above..
when I check my wfs by using uDig, it showed municipalities layers at :

http://localhost:8080/geoserver/wfs?VERSION=1.0.0&SERVICE=WFS&REQUEST=GetCapabilities#topp:municipalities

I  used Firebug for bug GET method but in console window's Firebug showed nothing, 

Could you please have a look for my protocol for 'municipalities' feature is it correct or not..? 
If it corrected please have a look down and note for other function if there is made errors for my searching function 


Many thanks 

Quang

The 1st thing you need when developing against any OWS (WMS,WFS,WMC,CWS,etc..) is a way to actually see the message to & response from the server. You can use Fiddler (PC Only) or Firebug (Firefox) or (to a much more limited degree) WebKit Developer Tools.

Without tools like this, you are really just shooting in the dark.

Assuming that all the code below is correct and you are using Geoserver, then you MUST get the featureNS value.
It is pretty easy, just logon to Geoserver and look at the layer list. We'll take the tiger:poi layer as an example.
On the Layers list you see Type, Workspace, Store, & Layer Name columns. The ones you are interested in are Workspace and Layer Name columns. For the tiger:poi example you can either use:
featureType:'tiger:poi', (that is the layer name with the namespace)
featureNS:'http://www.census.gov' (that is the Workspace URI)

-- OR --

featureType:'poi' (that is the layer name, without the namespace)
featureNS:'tiger' (that is the namespace, which is the same as the Workspace)

the first example is really the 'correct' way, but the second way works as well.

Hope that helps

NOTE: If you are using other servers, like Mapserver, then using namespaces can sometimes cause issues.

I wrote almost same the above example given, I change only in my data what I istalled in Geoserver 




 var protocol= OpenLayers.Protocol.WFS({        url: "http://localhost:8080/geoserver/wfs",        featureType: "municipaliteis",        //featureNS: "http://geovista.psu.edu/" I dont know how to fix this line    });    formPanel = new GeoExt.form.FormPanel({        title: "Place Name Search",        height: 150,        region: "north",        protocol: protocol,        items: [{            xtype: "textfield",            width: 200,            name: "name__like",            minLength: 4  
      },		xtype: "textfield",            width: 200,            name: "population__ge"		],        listeners: {            actioncomplete: function(form, action) {                features = action.response.features;                store.loadData(features);                vm=map.getLayersByName("Results");                if(vm.length===0){                    vecLayer = new OpenLayers.Layer.Vector("Results");                    map.addLayer(vecLayer);                    store.bind(vecLayer);                    select.bind(vecLayer);                }            }        },        buttons: [{text: 'search',            handler: function(){                formPanel.search();            }        }],        keys: [{ key: [Ext.EventObject.ENTER],             handler: function() {                formPanel.search();            }        }]    });I
 tried for all most one week to fix it, but it still not working... When I click to command button "search" it did not show any thing. If some one have experience about this work please write me a command.Thank in advance Quang
