How to know when service call completes

I have a function defined in the InlineJavaScript that executes a serviceCall control on the coach.    I want to wait for that service call to complete so I can get the data returned and use it.

The code in the function looks something like this:

var serviceCall=thisuiview.ui.get(“Service_Call1”);
serviceCall.execute();
var result = serviceCall.getResult();

…continue processing and use the result

There is a very small delay in the serviceCall.execute before the results come back (less that a second in my unscientific observations).   That causes the result to be null and the rest of the function to not behave as expected.

I tried adding a Do…While loop to wait for result to be not null.   But, I’m not happy with the performance – it added an almost 6 second delay.

Do you have a recommended way to wait for a service call to complete?

Cindy:

This is all asynchronous.  You would use the Service Call’s On Result (or On Error) event to know that the call has completed.

Hope this helps

Hi Cindy,

I am facing the same issue and wondering if you got a solution to this problem.

Tried calling the rest of the execution in the onResult event.  But no luck onResult event doesn’t get triggered before my java script function completes.

Thanks
