Hi Andy, I have the same problem. I solved it using a pretty simple component to format dates and numbers, actually a workaround...
the component is here http://wiki.apache.org/tapestry/Tapestry5OutputLocaleNumber and you use it inside your grid like this: <table t:type="grid" source="vpList" row="vpItem" > <t:parameter name="dateCell" > <span t:type="MyOutput" value="vpItem.date" format="literal:date(dd/MM/yyyy)" /> </t:parameter> </table> 2007/10/26, Andy Huhn <[EMAIL PROTECTED]>: > > Hello, > > I upgraded to 5.0.6, and since then, if I try to display a Grid that > contains a Date column whose value is NULL, I receive the following > exception. > > Should I file a JIRA, or am I doing something wrong? > > Here's the error: > > org.apache.tapestry.ioc.internal.util.TapestryException > Cannot format given Object as a Date > location > classpath:org/apache/tapestry/corelib/pages/PropertyDisplayBlocks.tml, > line 8, column 66 > 3 > <t:block id="enum"> > 4 > ${convertedEnumValue} > 5 > </t:block> > 6 > > 7 > <t:block id="date"> > 8 > <t:output > value="context.propertyValue" > format="dateFormat"/> > 9 > </t:block> > 10 > > 11 > </div> > * java.lang.IllegalArgumentException > Cannot format given Object as a Date > > Stack trace > * java.text.DateFormat.format(DateFormat.java:279) > * java.text.Format.format(Format.java:133) > * org.apache.tapestry.corelib.components.Output.beginRender( > Output.java:67) > * org.apache.tapestry.corelib.components.Output.beginRender( > Output.java) > * > org.apache.tapestry.internal.structure.ComponentPageElementImpl$10$1.run( > ComponentPageElementImpl.java:345) > * > org.apache.tapestry.internal.structure.ComponentPageElementImpl.invoke( > ComponentPageElementImpl.java:923) > * > org.apache.tapestry.internal.structure.ComponentPageElementImpl.access$100 > (ComponentPageElementImpl.java:69) > * > org.apache.tapestry.internal.structure.ComponentPageElementImpl$10.render( > ComponentPageElementImpl.java:349) > * org.apache.tapestry.internal.services.RenderQueueImpl.run( > RenderQueueImpl.java:58) > * > org.apache.tapestry.internal.services.PageMarkupRendererImpl.renderPageMarkup > (PageMarkupRendererImpl.java:40) > * > org.apache.tapestry.internal.services.PageResponseRendererImpl.renderPageResponse > (PageResponseRendererImpl.java:71) > * > org.apache.tapestry.internal.services.PageRenderRequestHandlerImpl.handle( > PageRenderRequestHandlerImpl.java:81) > * > org.apache.tapestry.internal.services.PageRenderDispatcher.dispatch( > PageRenderDispatcher.java:72) > * org.apache.tapestry.services.TapestryModule > $13.service(TapestryModule.java:1108) > * com.homeed.services.AppModule > $1.service(AppModule.java:82) > * > org.apache.tapestry.internal.services.LocalizationFilter.service( > LocalizationFilter.java:43) > * org.apache.tapestry.services.TapestryModule > $2.service(TapestryModule.java:688) > * > org.apache.tapestry.internal.services.StaticFilesFilter.service( > StaticFilesFilter.java:84) > * > org.apache.tapestry.internal.services.CheckForUpdatesFilter$2.invoke( > CheckForUpdatesFilter.java:97) > * > org.apache.tapestry.internal.services.CheckForUpdatesFilter$2.invoke( > CheckForUpdatesFilter.java:88) > * > org.apache.tapestry.ioc.internal.util.ConcurrentBarrier.withRead( > ConcurrentBarrier.java:77) > * > org.apache.tapestry.internal.services.CheckForUpdatesFilter.service( > CheckForUpdatesFilter.java:110) > * org.apache.tapestry.services.TapestryModule > $12.service(TapestryModule.java:1086) > * org.apache.tapestry.TapestryFilter.doFilter( > TapestryFilter.java:135) > * org.mortbay.jetty.servlet.WebApplicationHandler > $CachedChain.doFilter(WebApplicationHandler.java:821) > * org.mortbay.jetty.servlet.WebApplicationHandler.dispatch( > WebApplicationHandler.java:471) > * org.mortbay.jetty.servlet.ServletHandler.handle( > ServletHandler.java:568) > * org.mortbay.http.HttpContext.handle(HttpContext.java:1530) > * org.mortbay.jetty.servlet.WebApplicationContext.handle( > WebApplicationContext.java:633) > * org.mortbay.http.HttpContext.handle(HttpContext.java:1482) > * org.mortbay.http.HttpServer.service(HttpServer.java:909) > * org.mortbay.http.HttpConnection.service( > HttpConnection.java:816) > * org.mortbay.http.HttpConnection.handleNext( > HttpConnection.java:982) > * org.mortbay.http.HttpConnection.handle(HttpConnection.java > :833) > * org.mortbay.http.SocketListener.handleConnection( > SocketListener.java:244) > * org.mortbay.util.ThreadedServer.handle(ThreadedServer.java > :357) > * org.mortbay.util.ThreadPool > $PoolThread.run(ThreadPool.java:534) > > Thanks, > Andy > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > -- Atenciosamente, Marcelo Lotif
