Calling Webservices in a loop won't execute the custom OnSuccess function

I have a problem. I am coding using VS2008. I am calling webservices from my JavaScript Page. An example

Services.ChangeDropDownLists.GetNowPlayingMoviesByLocationSVC(
    blah, 
    OnSuccessMoviesByRegion, 
    OnError, 
    OnTimeOut
);

after execution, it goes to the function OnSuccessMoviesByRegion.

But if I put the Services in a loop (a simple for loop)

Services.ChangeDropDownLists.GetNowPlayingMoviesByLocationSVC(
    blah[i], 
    OnSuccessMoviesByRegion, 
    OnError, 
    OnTimeOut
);

OnSucessMoviesByRegion function won't execute (but the service call executes n times successfully But I must have the function cos I am returning value through it.

What am I missing? Is that the typical behaviour? Any alternatives?

Naveen, I'm answering your follow-up question here. I can think of two options:

  1. Try to make a single call packaging your data (sending the whole blah array and handle it on the server).

  2. Use a counter variable which you decrement in the "OnSucces" client handler each time and stop if this counter variable reaches 0.

I guess there is some kind of concurrency problem. Probably you fire the next request before the last one finished.

I think you'll have to rewrite the loop. Try to move that code, calling only the first request and then using the "OnSuccess" function to call the next one each time.
