Thanks Dan.
This was my code:
-----------------------------
#set($pagedListResponse = $core_v2_blog.List("%{UserId = $core_v2_user.Accessing.Id}"))
#foreach ($blog in $pagedListResponse)
<a href="$blog.Url">$blog.Name -- $blog.Url</a><br />
#end
------------------------------
--> I had missed the double quotes around the $blog.Url for the href. The problem was solved when i placed double quotes around it.
