Musachy Barroso resolved WW-2161.
---------------------------------
Resolution: Not A Problem
Please read the ajax tags documentation, the topic specified in "notifyTopics"
will be published before and after the request, that's why you will see 2 calls
to that function. A paremeter is passed to the topic which will be "before" ,
"load" (after request) or "error" if there was an error. On 2.1 we will have
separate topics for each case.
> subscription of ajax anchor tag is called repeatedly
