Hi Dmitrij,
Most likely svgElement is no in the rendering tree. This generally means that it either has 'display="none"' or is in a 'defs' section.
The other possibility is that the document is not setup to be 'dynamic' - which using the SVG DOM requires.
We should really check this in the call to getTransformToElement, but we don't.

Hi all,
I have the following code for transformation element coordinates to
screen:
Element root = svgElement.getOwnerDocument().getDocumentElement();
SVGMatrix matrix = ((SVGTransformable)
svgElement).getTransformToElement((SVGElement) root);
SVGPoint p = new SVGOMPoint(0, 0);
p = p.matrixTransform(matrix);
I receive the nullPointerException during the matrixTransform execution
java.lang.NullPointerException

Variables matrix and p are not null. What can be a problem?
