Getting runtime error when using the FindChildByXpath() Method if Object is not existed in page

It seems TC working as it supposed to

according to documents...........

if fails FindChild method returns a stub object that only contains the Exists property equal to False.

If the search failed, FindChildByXPath returns a null object

hence if you check exists property in findChild would not give error but FindChildByXPath would give error since there in no object.
