Hi Yazid, which version of tobago?
this is UIPopup in trunk: 69 70 public boolean isRendered() { 71 ValueBinding valueBinding = getValueBinding("rendered"); 72 if (valueBinding!= null) { 73 return (Boolean) valueBinding.getValue(getFacesContext()); 74 } else { 75 return isActivated() || isRedisplay(); 76 } 77 } 78 The only NPE in line 73 could be a autoboxing NPE when converting a null returned by valueBinding to boolean return value.
