Title: Chain Commands that Don't Execute Until Previous Command Does Post by: codecraig on September 09, 2008, 08:38:55 I have a MacroCommand and it executes Command A, B, then C. Currently B needs some data that A gets to do it's function. However, A calls a remote object asynchronously so it's 'execute' method finishes quickly and the MacroCommand calls B.execute.
Should I implement something that causes MacroCommand to wait for A to "finish" before calling B? or Should I create a special Proxy that stores the temporary results for me? Thanks!

Then it sits until a command finishes, then calls the next one. My subcommands actually modify the body of the notification as they move along.
works for me...anyone else try this? Title: Re: Chain Commands that Don't Execute Until Previous Command Does Post by: puremvc on September 10, 2008, 04:38:16 Have a look at Trilec's Notification Chaining utility:
