Cakephp ajax Autocomplete not working

I am using ajax 开发者_高级运维autocomplete in my application, but it is not giving the output. Ajax request to the desired function goes but it is not giving back any response, it is blank.

I am also using jquery but it is used for other effects. i added jquery no conflict to avoid the prototype & jquery conflicts.

I have tried other ajax helper methods like obeserverfield, it is working fine & returning the proper response, but when i use autocomplete it fails

Can anybody help me ..........

Ha..........

Finally i got solution of my problem.....

The problem was with the 'Security' component..

I searched, tried most of the ways & read a lot of post about the autocomplete issue, but no luck.

But while searching on google groups i got one hint & tried that solution & finally it work........

When i removed this component from the list then my auto complete started working properly...

Here is a question.....

Why this happens, is security component restricts the autocomplete actions or its an bug with the cakephp?
