Regarding the getRoster method in XMPPConnection Class

Hi,

*I am creating the XMPPConnection to the XMPPServer after that when

getRoster() method is called the roster items are fetched, but in my

scenario i need to use the same method frequently to fetch the updated

roster items, for which I am getting the same roster items, but I need

to get the updated roster items each time I call getRoster().*

Any help in this regard will be really helpful…Thanks in advance.
