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. ________________________________ From: flexcoders@yahoogroups.com [mailto:flexcod...@yahoogroups.com] On Behalf Of Tim Rowe Sent: Thursday, August 20, 2009 6:10 PM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] how to wait for more than one httpserivice/remoteobject result to finish? 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. --Tim ________________________________ From: flexcoders@yahoogroups.com [mailto:flexcod...@yahoogroups.com] On Behalf Of Wesley Acheson Sent: Friday, 21 August 2009 5:20 AM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] how to wait for more than one httpserivice/remoteobject result to finish? private var list1Result:ResultEvent; private var list2Result:ResultEvent; private function handleList1Result(event:ResultEvent):void { list1Result = event; if(list2Result) { handleResults(list1Result, list2Result); } } private function handleList2Result(event:ResultEvent):void { list2Result = event; if(list1Result) { handleResults(list1Result, list2Result); } } private function handleResults(result1:ResultEvent, result2:ResultEvent):void { //your code here } On Thu, Aug 20, 2009 at 8:35 PM, coder3 <rrhu...@hotmail.com <mailto:rrhu...@hotmail.com> > wrote: Hi my application needs to wait until two (or more) resultHandlers to get their results and use them together. for example, <mx:RemoteObject id="myRO" destination="test" fault="FaultHandler(event)"> <mx:method name="getList1" result="handleList1Result(event)"/> <mx:method name="getList2" result="handleList2Result(event)"/> </mx:RemoteObject> at application creationComplete, it calles myRO.getList1() and myRO.getList2() 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. thanks C -- View this message in context: http://www.nabble.com/how-to-wait-for-more-than-one-httpserivice-remoteo bject-result-to-finish--tp25067471p25067471.html <http://www.nabble.com/how-to-wait-for-more-than-one-httpserivice-remote object-result-to-finish--tp25067471p25067471.html> Sent from the FlexCoders mailing list archive at Nabble.com. ------------------------------------ -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt <http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt> Alternative FAQ location: https://share.acrobat.com/adc/document.do?docid=942dbdc8-e469-446f-b4cf- 1e62079f6847 <https://share.acrobat.com/adc/document.do?docid=942dbdc8-e469-446f-b4cf -1e62079f6847> Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.comYahoo <http://www.mail-archive.com/flexcoders%40yahoogroups.comYahoo> !
