dynamic change of display rendering

hi folks,

i have some simple svg that i use with their gvt root node to display it in existing java canvas.

....

GVTBuilder builder = new GVTBuilder();

Element svgRootElem = svgDoc.getDocumentElement();
GraphicsNode rootNode = builder.build(ctx,svgRootElem );

...

rootNode.paint( myDisplayContext );

this works pretty good.

What i want to do now is changing the display dynamically among 3 or 4 possible definitions stored in the svg.

I tried tu put a defs section in the svg,

<ellipse rx="299" ry="299" style="stroke: rgb(255, 255, 255); fill: rgb(255, 153, 0);" cx="300"
         cy="300"/>
    <path style="stroke: rgb(255, 255, 255); fill:rgb(255, 255, 255)" d="m300,300 l 212.1,-212.1
        a300 300 0 0 1 0 424.2 z"/>
    <path style="stroke: rgb(255, 255, 255); fill:rgb(255, 255, 255)" d="m300,300 l -212.1,-212.1
        a300 300 0 0 0 0 424.2 z"/>

</defs>
</svg>

and i tried to access it that way with no results :

Element elem = svgDoc.getElementById("display2");
GraphicsNode auxDisplayNode = ctx.getGraphicsNode(elem); <-- auxDisplayNode == null

Has someone ever done it? should i put it in a symbol section instead of defs?

have i to reconstruct a whole gvt tree (to have a root graphics node)?if i have, how can i do that?

every ideas welcome (even stupids, trust me i got a lot...;)

thanks,regards

Remy.
