Changing fieldLabel dinamically ?
How do I change a field's fieldLabel dinamically, i.e. after the field has been rendered, in ExtJS 4.0 ?

I suspect you'll have to doLayout on the form after changing the fieldLabel attribute - I can't see any easy way to get the dom element to force the change.
But why would you do this?

I was expecting to have a less obvious (and resource-hungry) way. Need to do it because a I need to change a field's label, of course
If anyone knows a better way, please tell me.

Sounds like you're trying to repurpose an existing form to take input for several different reasons. Sounds dodgy to me.

May I suggest you have a locale file containing all the correct language strings as "variables" and use those for your labels - then your server can push the right locale file in response to the original request, or if someone wants to change the language on the fly you dynamically load the new locale and redraw the whole app?
-- edit --
It's late and I didn't think this one through - the on the fly bit wouldn't work 'cos changing the locale wouldn't change all the data in the Ext object structures...

That's kind of what I already do, I was just trying to avoid to redraw the form.

If you really wanted to, you could iterate through each item and then query down to the label and update that element. Make sure you change the fieldLabel property also.Mitchell Simoens @SenchaMitch
