combobox problem

[nick saint]

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',
            root:'students'
        }, [{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>',
        displayField:'name',
        valueField: 'id',
        fieldLabel: 'Students',
        emptyText:'Select...',
        loadingText: 'Loading...',
        maxHeight: 100,
        allowBlank: false,
        editable:false,
        anchor:'100%',
        triggerAction: 'all',
        lazyRender:true,
        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
Nick

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
Nick
