RE: [flexcoders] how to wait for more than one httpserivice/remoteobject result to finish?
Tim makes a great point...
Events are great for tracking things, but you also have to be careful
not to have too many events waiting in your program. I have seen cases
where there are so many events waiting in a program that weird things
happen with them like the handler not getting the message that an even
has fired. If you're doing just a few events then you shouldn't have
that big of a deal. I try to keep my active events low and around 10-15
so that older and slow computers shouldn't have a problem.

You don't really get much in the way of thread control in Flex, but a
neater way might still be to create something of a pseudo-barrier.
At the time each object is fired, you would also add a token to the
barrier, latching it and increasing the counter on that token. Each
event listener could then call off to the barrier, passing the same
token fired as a property of the event to decrease against that token on
the barrier - at the point all tokens are unblocked (ie, reach 0) you
can open the barrier. Your other code would sleep (I was almost going
to say spinwait... hm, no :) until the barrier is unlatched.
This could avoid you needing to write a handler for each event - the
problem with the below example is what happens when you need three, or
four, of seven events to be waited on. Just something to give some
thought to anyway.

Hi
my application needs to wait until two (or more) resultHandlers to get

for example,
at application creationComplete, it calles myRO.getList1() and

what can i do to make sure i get both results before i do anything else?
i know it can call myRO.getList1(), then in the
handleList1Result(event:ResultEvent), after it gets the list1 result,
then
it calls myRO.getList2(),
but i would like to know a better, more clear way.

The data gets populated/manipulated in the result="...". If the data doesn't come in for some reason, the fault handler kicks in. You can pass customized values into the fault handler from your RDO as well. So, if your handleList1Result(event) function fires, then it has data. Then you can check for individual variables within that data set to make sure you have everything...

RE: [flexcoders] how to wait for more than one httpserivice/remoteobject result to finish?
This may be essentially the same thing Tim is suggesting, but you could set
a property on an associative array (Object) in the send function and delete
the corresponding property value in the result or fault handlers. When
for..in returns zero iterations, all calls have returned.
