Subject Re: Checking if a Target Exists
Date Thu, 03 Nov 2011 16:01:03 GMT
I was looking for a solution to this problem some time back :-). Didn't
know someone else might run into the same thing. I resorted to calling the
target without checking for its existence and ignoring the failure. No
longer working on that stuff :-).

Thanks Steve for asking and Vimil for suggesting the way out !

Will keep a watch on the thread if some implementation specific inputs are
shared.
