Flex 4 -Reloading an SWF within the application - apache-flex

Question

Rather than deal with trying to figure out the passing of parameters to an embedded SWF, I went ahead and made 20 SWF's all compiled with different values. These SWF's are now inside my Flash Builder application.
There is a state for each SWF (using includeIn) so when the user clicks the button to switch states, the appropriate SWF is displayed.
The problem is that when a user views an SWF, it remains loaded and running in the background. I would like to unload the viewed SWF when the user leaves the state and then load it when it is needed again. If this is not possible, then I will settle for simply reloading the SWF when the state is entered, and just leave the other 19 running in the background.
I have the following:
<fx:Script><![CDATA[
private var flashMovie1:MovieClip;
private var flashMovie2:MovieClip;
private function initFirst():void{
flashMovie1 = dmp_first.content as MovieClip;
}
private function initSecond():void{
flashMovie2 = dmp_second.content as MovieClip;
}
protected function btnFirst_clickHandler():void
{
flashMovie2.Stop();
currentState='First';
flashMovie1.Play();
}
protected function btnSecond_clickHandler():void
{
flashMovie1.Stop();
currentState='Second';
flashMovie2.Play();
}
]]></fx:Script>
<mx:SWFLoader id="dmp_first" includeIn="First" source="assets/images/dmp_first.swf" complete="initFirst()"/>
<mx:SWFLoader id="dmp_second" includeIn="Second" source="assets/images/dmp_second.swf" complete="initSecond()"/>
Along with the above code not working at all with the Stop and Play, I still can't figure out how to force an SWF to reload. Any help would be greatly appreciated!

You can have only one swf at a time using a conatiner. Also you donlt have to use states :) for ex:
<?xml version="1.0" encoding="utf-8"?>
<s:Application
xmlns:fx = "http://ns.adobe.com/mxml/2009"
xmlns:s = "library://ns.adobe.com/flex/spark"
xmlns:mx = "library://ns.adobe.com/flex/mx"
minWidth = "955"
minHeight = "600">
<s:layout>
<s:VerticalLayout/>
</s:layout>
<fx:Script>
<![CDATA[
import mx.controls.SWFLoader;
private function onAppCreationComplete():void
{
showSWF(0);
}
private function onSwfComboChange():void
{
showSWF(cbxSwfData.selectedIndex);
}
private function showSWF(index:int):void
{
grpContainer.removeAllElements();
var swfLoader:SWFLoader = new SWFLoader();
grpContainer.addElement(swfLoader);
swfLoader.load("assets/swfs_files/swf"+index+".swf");
}
]]>
</fx:Script>
<s:ComboBox
id = "cbxSwfData"
dataProvider = "{['swf1','swf2','swf3']}"
change = "onSwfComboChange()"/>
<s:Group
id = "grpContainer"
width = "50%"
height = "50%"/>
</s:Application>
