Re: BridgeContext.getElement returns null

Everything seems to be ok, but the BridgeContext always returns null !

  Your code looks quite confused to me..

|              GVTTreeWalker  treeWalker = new
GVTTreeWalker(e.getGVTRoot());

|               UserAgentAdapter userAgent = new UserAgentAdapter();
|                GVTBuilder builder         = new GVTBuilder();
|                BridgeContext ctx          = new BridgeContext(userAgent);
|                ctx.setDynamic(true);
|
|                 builder.build(ctx, theDocument);

   By doing this you are attaching a new GVT tree to 'theDocument'
You apparently already have a GVT tree (first line e.getGVTRoot()).
So I have to wonder why you are doing this?  Did you not
build the document dynamically the first time?  Doing this will
severely corrupt the document so it is a very bad idea...

|                 GraphicsNode root = theGVTTreeWalker.getRoot();
|                Point  point = new Point(nowToX, nowToY);
|
|                 // this (seems) to get the correct rectangle in the SVG
file (see below)
|                GraphicsNode childGNode = root.nodeHitAt(point);
|
|                // this comes up null every time
| - >>>>>  Element svgElement = theBridgeContext.getElement(childGNode);

   Almost none of the instances used here seem to be related to anything
that comes before, so I can't make sense of this.

       String targetNodeID = svgElement.getAttribute("id");

Here's the snipped SVG group:

<g id="guid_F917D459-6947-4C77-874B-9FED41DF5492">
   <g transform="translate(50,30)" style="font-size:11;
fill:rgb(230,230,245); font-family:&apos;Arial&apos;
stroke:rgb(230,230,245); stroke-width:1.5;">
    <rect x="180" y="189" width="35.2494" style="stroke:none;" height="63"
/>
    <rect x="180" y="189" width="35.2494" style="fill:none;
stroke:rgb(0,0,205);" height="63" />
