'smile_on.swf' is my application and 'http://www.sabljic-apartment.com/Smil/Shared/copyright.gif' is remote image that is loading in HorizontalList control. Image is loaded and displayed fine but i get above error after i click on it.

This application worked without any problems while i was using Flex Builder Beta 1 so i am in big trouble now and starting to panic. Can anyone help me with this error, how can i get rid of it? :eek:

thanks in advance

I got the following reply at flexcoders list regarding my problem:

Code:

That's a bug in the beta. A workaround is to subclass SWFLoader,
override notifyStyleChangeInChildren and regenerateStyleCache and have
them just return w/o doing anything.

So i guess that's something that can be solved but since i am no Flex expert, I don't know how the heck can i do that? I mean how can i "subclass SWFLoader and override notifyStyleChangeInChildren and regenerateStyleCache to have them just return w/o doing anything"? Can someone please be kind enough to explain this to me a little bit further?

thanks in advance

package{
class SWFLoaderBugFix extends SWFLoader{
public override function notifyStyleChangeInChildren ():void{}
public override function regenerateStyleCache ():void{}
}
}

First of all i'd like to thank you for your time and help, i really appreciate it. I have one more question though if it's not too much to ask. The thing is that all of my code which basically consists of few methods structured in my main .mxml file inside <mx:Script> tags like this:

Code:

---

<mx:Script>
<![CDATA[

...                   
...

public function Function1():void{
//do something
}


public function Function2():void{
//do something
}

...
...

]]>
</mx:Script>

---

And theese methods are called depending on various component events like "click" or something like that. So i don't know how to combine the OOP code you posted above with my "procedural" code since i am not using classes? Would it be enough to put the code you posted inside external .as file and use "include" statement in my main .mxml like this:

Code:

---

<mx:Script>
<![CDATA[

...                   
...

include "yourCode.as";

public function Function1():void{
//do something
}


public function Function2():void{
//do something
}

...
...

]]>
</mx:Script>

Or i have to do something else?

thank you very much
