Thanks for your suggestion once again. I tried to modify the displayField to
'name' and also 'type' but unfortunately I'm still getting nothing to show up
when clicking on the combo box. It says loading... Below it for a brief second
but nothing actually shows up, could this be a firewall or something? Maybe I
should try a featurestore instead with an added WFS layer, I will look into
that and post if I can make it work, thanks again for your suggestions.
Here is what I tried -
var neighbourhood_store = new GeoExt.data.AttributeStore({
url:
"http://localhost/RedWFS/request.aspx?REQUEST=describeFeatureType&SERVICE=WFS&version=1.1.0&typename=Neighbourhoods";
});
//Type dropdown
var neighbourhoodCombo = new Ext.form.ComboBox({
fieldLabel: 'Neighbourhood Name',
store: neighbourhood_store,
valueField: 'name',
emptyText: 'Pick a neighbourhood ...',
displayField: 'name'
});
var neighbourhoods = [{
bodyStyle: 'padding-right:5px;',
items: {
xtype: 'fieldset',
title: 'Neighbourhood Search',
autoHeight: true,
defaultType: 'checkbox', // each item will be a checkbox
items: [neighbourhoodCombo]
}
}];

In your case you need not load the store yourself, the combobox will
load it when needed.

Your AttribureStore doesn't work with a feature, so you shouldn't
expect store.feature to be defined. Binding a feature to an
AttributeStore corresponds to a specific use of AttributeStore.

You cannot set valueField, emptyText and displayField to
"NEIGHBOURHOOD_NAME". The AttributeStore stores attribute records,
whose fields are "name", "type", etc (edit AttributeStore.js and
AttributeReader.js for more information). I think you may want to set
these properties to "name" instead.
Hope it helps,
