I want to include an SVG in a cell of a datagrid table. I created a test
class which shows a blue square. The square displays just fine but when I
click on it an exception shows up in eclipse (see below). If I change the
<svg> to be a string, a span or an img, clicking on that works without
error. Could someone tell me what am i doing wrong? In the debugger the
target of the click event shows as [object SVGRectElement] whereas when I
flip the comments to, say, show an image instead of svg, the target is
'<img src='foo.png'>.

private class CustomCell extends AbstractCell<String> {
@Override
public void render(Cell.Context context, String value,
SafeHtmlBuilder sb) {
if (value == null) return;
// sb.append(SafeHtmlUtils.fromTrustedString(value.toString()));
// sb.append(SafeHtmlUtils.fromTrustedString("<span>"));
// sb.appendEscaped(value);
// sb.append(SafeHtmlUtils.fromTrustedString("</span>"));
// sb.append(SafeHtmlUtils.fromTrustedString("<img
src=\"foo.png\"/>"));
sb.append(SafeHtmlUtils.fromTrustedString("<svg><rect
height='8px' width='8px' fill='blue'/>"));
}
}
