Re: Replace an Element on DOMtree and refresh the jsvgcanvas.

You need to do your change to the DOMTree inside the UpdateManager thread (leave the repaint to Batik, you do not need to call it, as long as your changes are made in the update canvas thread).

�� jsvgCanvas.getUpdateManager().getUpdateRunnableQueue().invokeLater(new Runnable(){
public void run(){

�� // Make a copy of the element subtree suitable for inserting into doc2
�� Node dup = doc.importNode(gElement, true);
��
�� element.getParentNode().replaceChild(dup,element);
��
�� //alterar o valor
�� doc.getElementById("value"+uids[0]).getChildNodes().item(0).setNodeValue(value);

�� //ver resultado num ficheiro
�� svgCreator.writeXmlToFile("d:\\marinho\\svgbib\\tmp.svg", doc);
}});

Your variables need to be Class wide, or declared final to work.

Regards,
Andres.
