PrintTranscoder bug ?

[Johan Duflost]

Dear all,   I try to print a SVG document from an applet using PrintTranscoder. It works but when the printing is finished, all the interactive features of my svg document are lost and I get some error messages when an event is fired.   Here is the piece of code :       class OnClickPrintAction implements EventListener {                 public void handleEvent(Event evt) {             EventTarget evtTarget = ((DOMMouseEvent)evt).getTarget() ;             Element target = (Element)evtTarget ;             SVGDocument svgDoc = (SVGDocument)target.getOwnerDocument() ;             PrintTranscoder pt = new PrintTranscoder() ;             TranscoderInput ti = new TranscoderInput(svgDoc) ;             pt.transcode(ti, null) ;             try {                     pt.print() ;             } catch(PrinterException pe) {                     pe.printStackTrace() ;             }         }             }   Error messages :   java.lang.NullPointerException    at org.apache.batik.bridge.TextUtilities.convertTextAnchor(Unknown Source)    at org.apache.batik.bridge.SVGTextElementBridge.getAttributeMap(Unknown Source)    at org.apache.batik.bridge.SVGTextElementBridge.fillAttributedStringBuffer(Unknown Source)    at org.apache.batik.bridge.SVGTextElementBridge.buildAttributedString(Unknown Source)    at org.apache.batik.bridge.SVGTextElementBridge.computeLaidoutText(Unknown Source)    at org.apache.batik.bridge.SVGTextElementBridge.handleDOMAttrModifiedEvent(Unknown Source)    at org.apache.batik.bridge.BridgeContext$DOMAttrModifiedEventListener.handleEvent(Unknown Source)    at org.apache.batik.dom.events.EventSupport.fireEventListeners(Unknown Source)    at org.apache.batik.dom.events.EventSupport.dispatchEvent(Unknown Source)    at org.apache.batik.dom.AbstractNode.dispatchEvent(Unknown Source)    at org.apache.batik.dom.AbstractElement.fireDOMAttrModifiedEvent(Unknown Source)    at org.apache.batik.dom.AbstractAttr.setNodeValue(Unknown Source)    at org.apache.batik.dom.AbstractAttr.setValue(Unknown Source)    at org.apache.batik.dom.AbstractElement.setAttribute(Unknown Source)    at SpeciesApplet.showTip(SpeciesApplet.java:319)    at SpeciesApplet.access$100(SpeciesApplet.java:43)    at SpeciesApplet$OnMouseOverNextAction.handleEvent(SpeciesApplet.java:827)    at org.apache.batik.dom.events.EventSupport.fireEventListeners(Unknown Source)    at org.apache.batik.dom.events.EventSupport.dispatchEvent(Unknown Source)    at org.apache.batik.dom.AbstractNode.dispatchEvent(Unknown Source)    at org.apache.batik.bridge.BridgeEventSupport$Listener.dispatchMouseEvent(Unknown Source)    at org.apache.batik.bridge.BridgeEventSupport$Listener.dispatchMouseEvent(Unknown Source)    at org.apache.batik.bridge.BridgeEventSupport$Listener.mouseEntered(Unknown Source)    at org.apache.batik.gvt.event.AWTEventDispatcher.processMouseEvent(Unknown Source)    at org.apache.batik.gvt.event.AWTEventDispatcher.dispatchMouseEvent(Unknown Source)    at org.apache.batik.gvt.event.AWTEventDispatcher.dispatchEvent(Unknown Source)    at org.apache.batik.gvt.event.AWTEventDispatcher.mouseMoved(Unknown Source)    at org.apache.batik.swing.svg.JSVGComponent$1$MouseMovedRunnable.run(Unknown Source)    at org.apache.batik.util.RunnableQueue.run(Unknown Source)    at java.lang.Thread.run(Unknown Source)       java.lang.NullPointerException    at org.apache.batik.dom.svg.SVGStylableElement$StyleDeclaration.<init>(Unknown Source)    at org.apache.batik.dom.svg.SVGStylableElement.getStyle(Unknown Source)    at SpeciesApplet.hideTip(SpeciesApplet.java:335)    at SpeciesApplet.access$200(SpeciesApplet.java:43)    at SpeciesApplet$OnMouseOutNextAction.handleEvent(SpeciesApplet.java:879)    at org.apache.batik.dom.events.EventSupport.fireEventListeners(Unknown Source)    at org.apache.batik.dom.events.EventSupport.dispatchEvent(Unknown Source)    at org.apache.batik.dom.AbstractNode.dispatchEvent(Unknown Source)    at org.apache.batik.bridge.BridgeEventSupport$Listener.dispatchMouseEvent(Unknown Source)    at org.apache.batik.bridge.BridgeEventSupport$Listener.mouseExited(Unknown Source)    at org.apache.batik.gvt.event.AWTEventDispatcher.processMouseEvent(Unknown Source)    at org.apache.batik.gvt.event.AWTEventDispatcher.dispatchMouseEvent(Unknown Source)    at org.apache.batik.gvt.event.AWTEventDispatcher.dispatchEvent(Unknown Source)    at org.apache.batik.gvt.event.AWTEventDispatcher.mouseMoved(Unknown Source)    at org.apache.batik.swing.svg.JSVGComponent$1$MouseMovedRunnable.run(Unknown Source)    at org.apache.batik.util.RunnableQueue.run(Unknown Source)    at java.lang.Thread.run(Unknown Source)   Does anybody know why ?
