Ext Js combobox value after onchange is value instead of label - extjs

Question

Just getting frustrated by something that should be an easy fix, but I'm too simple minded to see it :)
I'm having a grid where 1 column is a combobox. The thing works just fine and the correct value is beeing sent through my ajax request, but after I edited the grid row, the combobox disappread and the value that comes into place is not the label, but the value.
editor: new Ext.form.field.ComboBox({
typeAhead: true,
lazyRender: true,
store: new Ext.data.ArrayStore({
fields: ['contact', 'contactLabel'],
data: [
[1,'Jan'],
[2,'Jeroen'],
[3,'Mattijs'],
[4,'Sven'],
[5,'Thomas'],
[6,'Yoran']
]
}),
valueField: 'contact',
displayField: 'contactLabel',
hiddenName: 'contact'
})
So what happens is that when I change the combobox to i.e.. "Thomas", the value of the cell becomes "5", instead of "Thomas". I thought that defining value/display fields would make a difference, but it does not.
Anyone that knows the answer?

Answer 1

I am not quite sure if I got you right. If so you will need a renderer for that. I guess the example below the code snipped should show you if you are meaning such a case.
// the renderer. You should define it within a namespace
var comboBoxRenderer = function(combo) {
return function(value) {
var idx = combo.store.find(combo.valueField, value);
var rec = combo.store.getAt(idx);
return (rec === null ? '' : rec.get(combo.displayField) );
};
}
// the edit combo
var combo = new Ext.form.ComboBox({
store: store,
valueField: "value",
displayField: "text"
});

Here's the complete code
Ext.create('Ext.data.Store', {
storeId:'simpsonsStore',
fields:['name', 'email', 'phone', 'id'],
data:{'items':[
{"name":"Lisa", "email":"lisa#simpsons.com", "phone":"555-111-1224","id": 0},
{"name":"Bart", "email":"bart#simpsons.com", "phone":"555-222-1234","id": 1},
{"name":"Homer", "email":"home#simpsons.com", "phone":"555-222-1244","id": 2},
{"name":"Marge", "email":"marge#simpsons.com", "phone":"555-222-1254","id": 3}
]},
proxy: {
type: 'memory',
reader: {

root: 'items'
}
}
});
// the combo store
var store = new Ext.data.SimpleStore({
fields: [ "value", "text" ],
data: [
[ 0, "Option 0" ],
[ 1, "Option 1" ],
[ 2, "Option 2" ],
[ 3, "Option 3" ]
]
});
// the renderer. You should define it within a namespace
var comboBoxRenderer = function(combo) {
return function(value) {
var idx = combo.store.find(combo.valueField, value);
var rec = combo.store.getAt(idx);
return (rec === null ? '' : rec.get(combo.displayField) );
};
}
// the edit combo
var combo = new Ext.form.ComboBox({
store: store,
valueField: "value",
displayField: "text"
});

Try:

{contact: 1, contactLabel: 'Jan'},
...
