Problem with url()

Hi,

First, sorry if a topic exist already about this problem , i have search but i didn't find.

So, I have a problem with function setStyle.

Indeed, when i want to apply a style which need "url()" in parameter like

background : url('./url/picture.png')

 It's work, but when they are a relative url like : "list-style-image('./test/picture.png'),the ckeditor parsor seem complete url like that : "list-style-image('http://localhost..../mywebappli/test/picture.png')".

commit : function( element ){
	var value = this.getValue();

	element.setStyle( 'list-style-image', 'url(' + value + ')' );
}

So my answer is , how to just let relative url ?

Thanks.

(sorry for bad english :p)
