    Default extjs 4 : get store record values

    My json data looks like this :

    Code:
    ({"success": "true", "message" : "OK","data":[{"id_metric":"1","name_filter":"doc filter","type_guicomp":"combobox"},{"id_metric":"1","name_filter":"severity","type_guicomp":"combobox"}]})
    I'd like to be able to retrieve the "type_guicomp":"combobox" value for the "id_metric":"1", so the result would be : "type_guicomp":"combobox" and "type_guicomp":"combobox".

    I do this because I need the value "combobox" to assign it to a variable, I've tried several things including :

    Code:
    myStore.load({
            scope: this,
            callback : function(record, operation, success) {
                console.log(record);
                console.log(record.data);
                }
    And :

    Code:
    var index = Ext.StoreMgr.lookup("myStore").findExact('id_metric',1);
    var rec = Ext.StoreMgr.lookup("myStore").getAt(index);
    console.log(rec);
    These solutions return undefined or null. So when I did this in the callback :

    Code:
    var i = myStore.getCount();
    console.log(i);
    It returned 0. But when I check the json output, it's not empty and there's actually data in it.
    My store looks like this :

    Code:
    Ext.define('Metrics.store.MyStore', {
        extend: 'Ext.data.Store',
        model: 'Metrics.model.MyModel',
        autoLoad: true,
    	idProperty: 'id_metric',
        proxy : {
    		type : 'ajax',
    		node : 'id_metric',
    		api : {
    		read : 'gui_comp_items.php'
    		},
    		reader: {
                type: 'json',
                successProperty: 'success',
                messageProperty: 'message',
                root: 'data'
            }}
    });
    My model :

    Code:
    Ext.define('Metrics.model.MyModel', {
        extend: 'Ext.data.Model',
        fields: [
    	{name : 'id_metric', type : 'int'},
    	{name : 'name_filter', type : 'string'},
    	{name : 'type_guicomp', type : 'string'},
    	{name : 'value', type : 'string'}]	
    });
    Pleaaase try to help me on this one, thank you!

    Default

    Please share the code of creating the store too, may be issue lies there, as here you have shared the code of defining it alone.
