[OpenLayers-Users] How can I overwrite the url ofOpenLayers.Protocol.HTTP?

[Gery .]

Hi Arnd,

Thanks for the answer and the tip, I tried it but with GeoExt.form.formPanel didn't work, I will take the protocol out of this formPanel and will try that. Without testing it I think it should be a scope problem, because the .refresh({}); function will be calling the protocol which is outside the listeners function, but will try it.

Any other suggestions are very welcome, thanks

Gery

Hi Gery,
 
this is the way without GeoExt :
myVectorLayer.refresh({url: newUrl});

Hi 
all,

How can I overwrite the url of OpenLayers.Protocol.HTTP? I tried 


> searchformPanel.protocol.url

and it works (checked with 
console.log), but at the end the original url is sent (in the code below: url: 
'/fs/') (see attached picture).

![output from firebug][1]

This is 
the code: 

    var searchformPanel = new 
GeoExt.form.FormPanel({
      border: 
false,
      width: 
250,
      protocol: new 
OpenLayers.Protocol.HTTP({
        url: 
'/fs/',
        format: new 
OpenLayers.Format.GeoJSON()
      
}),
      
items:[{
        xtype: 
'combo',
        id: 
'idcombo',
        store: new 
Ext.data.SimpleStore({
          
fields:['fsclass','ollayer'],
          
data:[["Boreholes","Boreholes"],["All_layers","All 
layers"]]
        
}),
        displayField: 
'ollayer',
        valueField: 
'fsclass',
        fieldLabel: 
'Layer',
        emptyText: 'select a 
layer',
        submitValue: 
false,
        selectOnFocus: 
true,
        mode: 
'local',
        typeAhead: 
true,
        editable: 
false,
        forceSelection: 
true,
        triggerAction: 
'all'
      
},{
        xtype: 
'textfield',
        id: 
'idtextfield',
        fieldLabel: 'Find 
features',
        emptyText: 'enter 
word',
        name: 
'comments__like',
        allowBlank: 
false
      }],
      
listeners:{
        actioncomplete: 
function(form, 
action){
          
searchShowTip(action.response.features);
        
}
      },
      
buttons:[{
        text: 
'search',
        
listeners:{
          click: 
function(){

            
var comboLayer = 
Ext.getCmp('idcombo').getRawValue();
            
var keyword = 
Ext.getCmp('idtextfield').getRawValue();

            
var newUrl = '/fs/' + comboLayer + '?format=GeoJSON&comments__ilike=' + 
keyword + 
'&queryable=comments';
            
console.log('1:' + 
newUrl);

            
//this gets '/fs/' from the 
searchformPanel
            
console.log('2:' + 
searchformPanel.protocol.url);

            
searchformPanel.protocol.url = 
newUrl;
            
console.log('3:' + 
searchformPanel.protocol.url);

            
searchformPanel.search();
          
}
        
}
      }]
  });

Please any support 
about this is very welcome, thank you!
