Change iconCls on the fly

[joefox]

I have a javascript function that changes the Text and iconCls on my form on the fly.
I can change the Text but the i throw an error when trying to change the iconCls

Any ideas?

var mtr = Ext.ComponentMgr.get('spec_filter_button');
mtr.setText('CHANGED');
mtr.seticonCls('user_edit');

Didn't you already ask this?

It's setIconClass (capital I + Class).
