ComboBox, onSelect and superclass

[deuns]

Hi

I'm french and I'm new with extjs.

I'm trying to use the comboBox component, and i've got some problems.
I need to extend the select event of the combobox. I've read that when i use the onSelect i override the superclass event. I want to call this event but I don't know how to do.
I've saw how to call a method but i suppose events aren't methods...

If somebody can help me (just explain, I want to learn !!!).

I show you my code :

var store_Fournisseur = new Ext.data.JsonStore({
		// The url to send the request to
		url: '../ajax/index.php?a=libelleFournisseur',
		// What fields would you like mapped from the returned JSON
		fields: ['libelleFournisseur', 'id_fournisseur', 'referenceFournisseurAstel', 'addresseFournisseur', 'cleRIB'], 
		root: 'fournisseurs', // The object in your JSON that holds your records
		totalProperty: 'record_count', // The object in JSON that holds the total count
		autoLoad: true // Load the data automatically upon JSON store creation
	})
	var comboFournisseur = new Ext.form.ComboBox({
	    store: store_Fournisseur,
	    displayField:'libelleFournisseur',
	    typeAhead: true,
	    mode: 'local',	//necessaire pour afficher le chargement
	    triggerAction: 'all',
	    emptyText:'Choisir un fournisseur...',
		hideTrigger: false,
	    selectOnFocus:true,
	    applyTo: 'libelleFournisseur',
		onSelect: function(store_Fournisseur){
			if(this.isExpanded()){
				this.collapse();
			}
			var referenceFournisseurAstel = document.getElementById('referenceFournisseurAstel');
			referenceFournisseurAstel.value = store_Fournisseur.data.referenceFournisseurAstel;
			var addresseFournisseur = document.getElementById('addresseFournisseur');
			addresseFournisseur.value = store_Fournisseur.data.addresseFournisseur;
			var cleRIB = document.getElementById('cleRIB');
			cleRIB.value = store_Fournisseur.data.cleRIB;
		}
	});

When I delete the onSelect code, combobox functions (offcourse ^^) but, as you can see, i want to update other fields (when i select an item).

Thank you for your help and sorry about my poor english :/

I see that i've made a mistake... I use the 2.x extjs not the 1.x. If somebody could move my thread... ?!!

thx =)

Please, some help will be really appreciated. I didn't find some codes or examples which explain on how to do. I read again and again API but there's nothing.... :/

I'm just looking for how to call the default listener onSelect of the comboBox, in order to extends his functionality.

Great thanks

I don't find the answer, and i need your help.
The problem is that the combobox doesn't select the item i want. It selects the first proposition in the list. That's why i need to call the default action of the combobox.
Thanks.

You might have a start by checking the tutorial on extending a class. There is also a stickied thread in the 2.0 forum that's a little more descriptive.

The extension is coincidentally about comboBox.

I have already read the tutorial, and tried to extend "MyComboBox", without results, I will read your link in details. Thanks again =)

Alright, good job.

It will help other users if you post your final solution, and especially if you include a few comments either in your code or outside of it, that describe what you needed to do to solve your problem.
