Description

Dynamic modification of gradients doesn't work in Batik:

<?xml version="1.0" encoding="iso-8859-1"?>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1"
viewBox="-1 -1 4 4" onload="Init()">
<script type="text/ecmascript"><![CDATA["use strict";
var SVG= "http://www.w3.org/2000/svg";
function Init()

{ var elt= document.createElementNS( SVG, "stop" ); elt.setAttribute( "offset", "0" ); document.getElementById( "grad" ).appendChild( elt ); }

]]></script>
<linearGradient id="grad"/>
<rect id="rect" width="2" height="2" fill="url(#grad)"/>
</svg>

This should display a black square. In Batik, this works only after removing and re-setting the fill attribute:

document.getElementById( "rect" ).removeAttribute( "fill" );
document.getElementById( "rect" ).setAttribute( "fill", "url(#grad)" );
