NumberField validation does not fire after override of afterRender

[apachejo]

The code below was used to override the afterRender of Ext.form.Field to allow quicktips for the fields and their labels by supplying a field config option for quicktips (ex. qtipCfg:{title:"Title", text:"Text"}). The code was copied from another thread and modified slightly. It seemed to work fine. Then, I noticed that the field validators are not firing after overriding. Also, a NumberField will allow alpha characters after overriding.

This is used in an Ext 1.1.1 solution.

Any ideas?

Thanks.

Ext.override(Ext.form.Field, {
  	afterRender : function() {   
  		Ext.form.Field.superclass.afterRender.call(this);
        if (this.qtipCfg){
        	Ext.QuickTips.register({target:this.getEl(), title:this.qtipCfg.title, text:this.qtipCfg.text, enabled: true});
    		var label = findLabel(this);
    		if (label) {Ext.QuickTips.register({target:label, title:this.qtipCfg.title, text:this.qtipCfg.text, enabled:true});}
  		}
  	}
});
		});

	var findLabel = function(field) {	    
	    var wrapDiv = null; label = null
	    wrapDiv = field.getEl().up('div.x-form-element');
	    if (wrapDiv) {label = wrapDiv.child('label');}
	    if (label) {return label;}
	    wrapDiv = field.getEl().up('div.x-form-item');
	    if (wrapDiv) {label = wrapDiv.child('label');}
	    if (label) {return label;}    
	}

Try to add this.callParent(arguments) in the end of the overridden method
