I have seen a lot of codes regarding how to bind property in Flex project. Such as this code in Flex Help: var watcherSetter:ChangeWatcher = BindingUtils.bindSetter(updateMyString, myTI, "text");
However, I am creating Actionscript class within Actionscript Project, and I cannot import mx.binding.utils.* into my project. How could I make this works when Actionscript project cannot see this package? Is there any other way to makes property of different object bind together in Actionscript project?
