Hi, I have a problem with combobox.
The code is

var mainSS = new Ext.data.JsonStore({
proxy: new Ext.data.HttpProxy({url: '<?= HTTP_SERVER;?>json/settings/allSuplList.php' }),
reader: new Ext.data.JsonReader({
id: 'allCntrList',
totalProperty: 'total',
}, [{name: 'name'}, {name: 'id'}])

var mainS = new Ext.form.ComboBox({
store: mainSS,
hiddenId: 'id',
hiddenName: 'suplId',
tpl: '<tpl for=\".\"><div ext:qtip=\"{name}\" class=\"x-combo-list-item\">{name}</div></tpl>',
valueField: 'id',
fieldLabel: 'Students',
loadingText: 'Loading...',
maxHeight: 100,
allowBlank: false,
triggerAction: 'all',
forceSelect: true,
listClass: 'x-combo-list-small'
I definitely know that the store is getting the data.

{students: [
{ name:'Ivan J', id:'17'},
{ name:'Anna H', id:'6'},
{ name:'Nick F', id:'4'}
With the previous EXT version everything was ok but since ext-3.0-rc2 I had a few things I really do not understand.
Please, help to solve this one.

"Have a problem with Combobox" doesn't tell us anything.

Please review the JsonStore doc - there is no reader config. A JsonReader is internally configured.

Hi, thank you for reply.
You were right I had a few thing wrong. The store now is like this

var store = new Ext.data.JsonStore({
// store configs
//autoDestroy: true,
url: '<?= HTTP_SERVER;?>json/settings/allSuplList.php',
storeId: 'allCntrList',
// reader configs
root: 'students',
idProperty: 'name',
fields: ['name', 'id']

But a combo still does not work. I have read the JsonStore docs. The server returns the right type of data. Console confirms the data relieved.
Please, helpl to get it running.
Thank you

I found the problem. The old version does work but I couldn't see the selector items list. The thing is that the list appears behind the window. As I said I was using the desktop interface and I had something similar with window z-indexes. In the forum I have found this: Ext.WindowMgr.zseed = 50000;.
Is there any way to do the same with combo list items?
Thank you
