What is the difference between the following two methods in session object. attirbutRemoved(HSBE event) and attributeUnboundinvoked(HSBE event). I dont understand the difference between the above two methods. Any explanation is appreciated. Thanks in advance.
attirbuteRemoved(HSBE event) is used to notify that Session that some attributes of Session have been removed. and attributeUnboundinvoked(HSBE event) is used to notify the attributes/objects added to Seesion.( The attributes must be objects to receive event.)
