Hi, i keep getting an error whenever i enter a TriggerField (have a popup when i enter):

Code:
Error: this$static is undefined
Here´s a code snipet that i got from firebug:

Code:
function com_extjs_gxt_ui_client_widget_Component_$addStyleName__Lcom_extjs_gxt_ui_client_widget_Component_2Ljava_lang_String_2(this$static, style){
  if (this$static.com_extjs_gxt_ui_client_widget_Component_rendered) {
    com_extjs_gxt_ui_client_core_El_$addStyleName__Lcom_extjs_gxt_ui_client_core_El_2Ljava_lang_String_2((com_extjs_gxt_ui_client_core_El_$clinit__() , com_extjs_gxt_ui_client_core_El_global.com_extjs_gxt_ui_client_core_El_dom = this$static.getElement__() , com_extjs_gxt_ui_client_core_El_$clinit__() , com_extjs_gxt_ui_client_core_El_global), style);
  }
   else {
    this$static.com_extjs_gxt_ui_client_widget_Component_cls = this$static.com_extjs_gxt_ui_client_widget_Component_cls == null?style:this$static.com_extjs_gxt_ui_client_widget_Component_cls + $intern_226 + style;
  }
}
Another error when i enter a lookup field:

Erro: [Exception... "'java.lang.ClassCastException' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)" location: "<unknown>" data: no]

The last one might be leading to the second...

Any ideas?
