I've got a form that posts multiple values for a request parameter (multiple instances of <input type="text" name="paramName"/>).
request.getParameterValues() returns a String[] with an element for each posted value. If nothing is entered into into one of the text fields the corresponding element in the String[] is null, but this isn't handled by <xsp-request:get-parameter-values. The stacktrace is included in the following patch to fix the problem: --- XSPRequestHelper.java.1.11 Tue Jun 4 15:32:54 2002 +++ XSPRequestHelper.java Tue Jun 4 15:05:28 2002 @@ -68,8 +68,19 @@ /** * The <code>Request</code> object helper + * <pre> + * Modified by Pinnacle Software to fix: + * + * java.lang.NullPointerException + * at org.apache.cocoon.components.language.markup.xsp.XSPObjectHelper.data(XSPObj ectHelper.java:196) + * at org.apache.cocoon.components.language.markup.xsp.XSPObjectHelper.elementData (XSPObjectHelper.java:93) + * at org.apache.cocoon.components.language.markup.xsp.XSPRequestHelper.getParamet erValues(XSPRequestHelper.java:291) + * at org.apache.cocoon.www.pinnacle.assetComponents_xsp.generate(C:\jakarta-tomca t-4.0.4-b3\work\Standalone\localhost\cocoon\cocoon-files\org/apache/cocoon/w ww/pinnacle\assetComponents_xsp.java:1299) + * at org.apache.cocoon.generation.ServerPagesGenerator.generate(ServerPagesGenera tor.java:260) + * </pre> * * @author <a href="mailto:[EMAIL PROTECTED]";>Ricardo Rocha</a> + * @version Modified from Apache's version CVS Id: XSPRequestHelper.java,v 1.11 2002/02/27 05:33:50 vgritsenko Exp * @version CVS $Id: XSPRequestHelper.java,v 1.1 2002/06/04 04:52:31 neil Exp $ */ public class XSPRequestHelper { @@ -278,15 +289,18 @@ String[] values = request.getParameterValues(name); if (values != null) { for (int i = 0; i < values.length; i++) { - if(form_encoding != null && values[i] != null && - values[i].length() > 0) { - try { - values[i] = new String(values[i].getBytes(container_encoding), - form_encoding); - } catch(java.io.UnsupportedEncodingException uee) { - throw new RuntimeException("Unsupported Encoding Exception: " + - uee.getMessage()); - } + if (values[i] != null) { + if(form_encoding != null && values[i].length() > 0) { + try { + values[i] = new +String(values[i].getBytes(container_encoding), + form_encoding); + } catch(java.io.UnsupportedEncodingException uee) { + throw new RuntimeException("Unsupported Encoding +Exception: " + + uee.getMessage()); + } + } + } else { + values[i] = ""; } XSPObjectHelper.elementData(URI, PREFIX, contentHandler, "value", values[i]); --------------------------------------------------------------------- Please check that your question has not already been answered in the FAQ before posting. <http://xml.apache.org/cocoon/faqs.html> To unsubscribe, e-mail: <[EMAIL PROTECTED]> For additional commands, e-mail: <[EMAIL PROTECTED]>
