combobox - loading

[Bleak]

I'm struggling with what is probably a simple problem, but I just can't seem to get past it. The issue is that I have a form that contains a combobox that is loaded from a remote store, the initial display is working, the problem I am having is reloading the data back into the form.

My combobox is defined as

                                           {
                                                xtype           : 'combo',
                                                fieldLabel      : 'Project Sponsor',
                                                anchor          : '-10',
                                                loadingText     : 'Querying...',
                                                minChars        : 1,
                                                forceSelection  : true,
                                                triggerAction   : 'all',
                                                displayField    : 'user',
                                                valueField      : 'id',
                                                hiddenName      : 'sponsor_id',
                                                store           : this.dao.getUsersByGroup('SPONS'),
                                                mode            : 'remote'
                                            } 

The store returns data defined by the record

                  [
                        {name: 'id'},
                        {name: 'user'},
                        {name: 'group'}
                    ] 

So, this all saves properly and looks good. However, for the life of me I can not get the data to load from a record. It always displays the id in the combobox instead of the text value. The record that comes back from the server when a record is loaded is defined as;

                    [
                          {name: 'id'},
                          {name: 'sponsor_id'},
                          {name: 'manager_id'},
                          {name: 'subscriber_id'},
                    ] 

The value I want to be updated in the form's combobox is the sponsor_id from this record.

The issue is that the associated combobox has not yet been loaded, so no values exists in the drop-down for the match.

I recommend this override.

Thanks Condor, worked perfectly.
