flash movie with MAFileModel and SWFObject

[Esteban Lorenzano]

Hi,
I'm trying to render some uploaded files as flash movies... but without 
success by now... I thought it was easy, just putting this method in 
MAFileModel (and of course, changing #renderOn:)

:

renderFlashOn: html
	html swfObject
		url: (self urlOn: html);
		with: 'Loading...'.

But nothing happens (it shows "Movie not loaded...")

If I put an "example" url, the example movie is loaded ok... :(

renderFlashOn: html
	html swfObject
		url:  'http://www.mariaclaudiacortes.com/colors/Colors.swf';
		with: 'Loading...'.

So I think there is something in the URL  generated by #urlOn: that is 
not good for swfObject  (writing the html code directly drives to the 
same answer)...

Any idea?
Thanks,
Esteban
