Write text in another tab by clicking on combobox

[Sandrine]

Hi all,

I need some help.

I have a modal window, separate in two parts.
Left : my store in combobox.
Center : three tabs.
When i choose one thing in my combobox i want to write a text in my first tab.
You know what i mean?

    var store = new Ext.data.SimpleStore({
        fields: [ 'state'],
        data : exampleData
    });
    var combo = new Ext.form.ComboBox({
        store: store,
        displayField:'state',
        typeAhead: true,
        mode: 'local',
        emptyText:'Selection...',
        selectOnFocus:true
       ,listeners:{select:{fn:function(combo, value) {
                        alert( combo.getValue());
                        genre.body.update('some text');//genre -> first tab's id 
                        }}
                    }

    });

How can i do that?
IF you have idea... Thanks

That looks like the right way to go about it, what's the problem?

It's written :
genre.body is undefined .
Sniff

Ok, well you can't just treat a string as though it's a variable.

You need to either
a) Keep a reference to the tab when you create it
b) Use Ext.getCmp() to retrieve the component instance

[Sandrine]

alert( combo.getValue()); => it works
alert( Ext.getCmp('combo').getValue()); =>it doesnt work

Ext.getCmp("combo") is undefined

Did i forget something?

[evant]

Wrong thing.

combo is a valid variable. genre is not, that's where you need getCmp. I'd suggest you read the documentation to understand why you need to do that.
