SVG problem

Hi,
this time i'm trying to create SVG's. The problem is: i create a big SVG canvas and then add "path" children to it, but they are not shown.

example:

var SVGcanvasNode = myScene.addChild();
var SVGcanvasDOM = new DOMElement(SVGcanvasNode , {tagName:"svg"});

/_here various setAttribute to set the svg_/

var pathNode= SVGcanvasNode .addChild();
var pathDOM= new DOMElement(pathNode, {tagName:"path"});

/_here various setAttribute to set the path_/

nodes are added to the DOM, but they are not visible in the page.
If i edit the code in Google Chrome just adding, for example, a blank space with the spacebar, everything comes out.

Thanks in advance for the help!
