Sergiu Dumitriu commented on XWIKI-1849:
----------------------------------------
This is caused by the fact that there is no order of the requests. The
equivalent of a multithreading issue in the AJAX world...
If I quickly type 'vincent', 7 requests (or more?) are made to the server, and
the responses don't always come in the right order. This means that the results
for 'vincent' might come before the results for 'vinc', thus the actual results
will be those for 'vinc'.
Another situation, given the asynchronous nature of the requests, is when more
callbacks are trying to update the table at the same time, and a table with
results from multiple filters is created. For example, I managed to get the
same user listed twice.
We could fix this by returning the queried string in the response, and if we
get a response that doesn't match the expected request, then ignore it.
Also, we should have a delay between the typing and the request, so that if I
quickly type 'vincent', I don't make 7 requests, but one after I enter all the
letters.
