[flexcoders] Binding visibility based on class property

[Paul Steven]

I want to set the visibility of an embedded swf file based on the property
of a class 

 

Here is what I am trying but it does not work and I get a warning saying -
Data binding will not be able to detect assignments to "uploadingFile"

 

<mx:SWFLoader visible="{_session.uploadingFile}"
source="@Embed('assets/uploadingFileAnim.swf')" id="uploadingFileAnim"/> 

 

Any ideas how I can get this to work?

 

In my session class, I have the following:

 

                                public function set
uploadingFile(passedValue:Boolean){

                                                

                                                _uploadingFile =
passedValue;

                                                

                                }

                                

                                public function get uploadingFile():Boolean
{

                                                

                                                

                                                return _uploadingFile;

                                }
