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.
