Combobox Should have a option for don't fire the change Event when using setValue()

[tanmayasahu]

Hi ExtJS Dev Team,
I am facing a issue with combobox setValue() method. My requirement is not to fire the change event of combobox, when I am setting the value using setValue(). Any way I have solved the problem by overriding the the setValue() method. But I think it is better to give a optional boolean parameter in the setValue() to use or avoid the change event.

Thanks...

Hi Scott,
SetRawValue() is for setting the displayValue, it will not change the value field of the combo am I right ?
I want the value of the combobox will get changed and the change event should not fire.

Thanks

Please see the following:

Ext.application({
    name : 'Fiddle',

    launch : function() {

        var states = Ext.create('Ext.data.Store', {
            fields: ['abbr', 'name'],
            data : [
                {"abbr":"AL", "name":"Alabama"},
                {"abbr":"AK", "name":"Alaska"},
                {"abbr":"AZ", "name":"Arizona"}
            ]
        });
        
        var combo = Ext.create('Ext.form.ComboBox', {
            fieldLabel: 'Choose State',
            store: states,
            queryMode: 'local',
            displayField: 'name',
            valueField: 'abbr',
            renderTo: Ext.getBody()
        });
        
        combo.on('change', function(combo){
           console.log('--- change ---'); 
           console.log(combo.getValue()); 
        });
        
        combo.setValue('AK');
        
        setTimeout(function(){
            console.log('--- set raw ---'); 
	        combo.setRawValue('AZ');
	        console.log(combo.getValue()); // value, but no change event
        },1000);

    }
});

Hi Scott, Thanks for sharing the example, Actually I was passing the raw value to the setRawValue() method. That was my mistake.....
