javax.faces.FacesException: Expression Error: Named Object: player not found

java, jsf, jsf-2, primefaces

Solution

It's basically telling that the JSF `Converter` with the ID "player" cannot be found. It's been referenced as `<p:pickList converter="player">`.

With the given code, you need to register the `PlayerConverter` as follows in `faces-config.xml`.

<converter>
    <converter-id>player</converter-id>
    <converter-class>org.primefaces.examples.view.PlayerConverter</converter-class>
</converter>

Alternatively, you could edit the `PlayerConverter` class to add the annotation

@FacesConverter("player")

on the class.

Problem

I am trying to learn pickList from Primefaces. What I have jsf file, PickListBean.java and Player.java. When I run the project, I get error as `http://code.google.com/p/primefaces/source/browse/examples/trunk/showcase/src/main/java/org/primefaces/examples/domain/?r=3692`. Stacktrace as below. ``` javax.faces.FacesException: Expression Error: Named Object: player not found. at com.sun.faces.application.ApplicationImpl.createConverter(ApplicationImpl.java:1338) at com.sun.faces.facelets.tag.jsf.ValueHolderRule$LiteralConverterMetadata.applyMetadata(ValueHolderRule.java:85) at com.sun.faces.facelets.tag.MetadataImpl.applyMetadata(MetadataImpl.java:81) at javax.faces.view.facelets.MetaTagHandler.setAttributes(MetaTagHandler.java:129) at javax.faces.view.facelets.DelegatingMetaTagHandler.setAttributes(DelegatingMetaTagHandler.java:102) at com.sun.faces.facelets.tag.jsf.ComponentTagHandlerDelegateImpl.doNewComponentActions(ComponentTagHandlerDelegateImpl.java:409) at com.sun.faces.facelets.tag.jsf.ComponentTagHandlerDelegateImpl.apply(ComponentTagHandlerDelegateImpl.java:159) at javax.faces.view.facelets.DelegatingMetaTagHandler.apply(DelegatingMetaTagHandler.java:120) at javax.faces.view.facelets.CompositeFaceletHandler.apply(CompositeFaceletHandler.java:98) at javax.faces.view.facelets.DelegatingMetaTagHandler.applyNextHandler(DelegatingMetaTagHandler.java:137) at com.sun.faces.facelets.tag.jsf.ComponentTagHandlerDelegateImpl.apply(ComponentTagHandlerDelegateImpl.java:184) at javax.faces.view.facelets.DelegatingMetaTagHandler.apply(DelegatingMetaTagHandler.java:120) at javax.faces.view.facelets.DelegatingMetaTagHandler.applyNextHandler(DelegatingMetaTagHandler.java:137) at com.sun.faces.facelets.tag.jsf.ComponentTagHandlerDelegateImpl.apply(ComponentTagHandlerDelegateImpl.java:184) at javax.faces.view.facelets.DelegatingMetaTagHandler.apply(DelegatingMetaTagHandler.java:120) at javax.faces.view.facelets.CompositeFaceletHandler.apply(CompositeFaceletHandler.java:98) at com.sun.faces.facelets.compiler.NamespaceHandler.apply(NamespaceHandler.java:93) at javax.faces.view.facelets.CompositeFaceletHandler.apply(CompositeFaceletHandler.java:98) at com.sun.faces.facelets.compiler.EncodingHandler.apply(EncodingHandler.java:86) at com.sun.faces.facelets.impl.DefaultFacelet.apply(DefaultFacelet.java:152) at com.sun.faces.application.view.FaceletViewHandlingStrategy.buildView(FaceletViewHandlingStrategy.java:774) at com.sun.faces.lifecycle.RenderResponsePhase.execute(RenderResponsePhase.java:100) at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:101) at com.sun.faces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:139) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:594) at org.apache.catalina.core.StandardWrapper.service(StandardWrapper.java:1542) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:281) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.apache.catalina.core.StandardPipeline.doInvoke(StandardPipeline.java:655) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:595) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:161) at org.apache.catalina.connector.CoyoteAdapter.doService(CoyoteAdapter.java:331) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:231) at com.sun.enterprise.v3.services.impl.ContainerMapper$AdapterCallable.call(ContainerMapper.java:317) at com.sun.enterprise.v3.services.impl.ContainerMapper.service(ContainerMapper.java:195) at com.sun.grizzly.http.ProcessorTask.invokeAdapter(ProcessorTask.java:849) at com.sun.grizzly.http.ProcessorTask.doProcess(ProcessorTask.java:746) at com.sun.grizzly.http.ProcessorTask.process(ProcessorTask.java:1045) at com.sun.grizzly.http.DefaultProtocolFilter.execute(DefaultProtocolFilter.java:228) at com.sun.grizzly.DefaultProtocolChain.executeProtocolFilter(DefaultProtocolChain.java:137) at com.sun.grizzly.DefaultProtocolChain.execute(DefaultProtocolChain.java:104) at com.sun.grizzly.DefaultProtocolChain.execute(DefaultProtocolChain.java:90) at com.sun.grizzly.http.HttpProtocolChain.execute(HttpProtocolChain.java:79) at com.sun.grizzly.ProtocolChainContextTask.doCall(ProtocolChainContextTask.java:54) at com.sun.grizzly.SelectionKeyContextTask.call(SelectionKeyContextTask.java:59) at com.sun.grizzly.ContextTask.run(ContextTask.java:71) at com.sun.grizzly.util.AbstractThreadPool$Worker.doWork(AbstractThreadPool.java:532) at com.sun.grizzly.util.AbstractThreadPool$Worker.run(AbstractThreadPool.java:513) at java.lang.Thread.run(Thread.java:680) ``` When I run the project, I get error as `http://code.google.com/p/primefaces/source/browse/examples/trunk/showcase/src/main/java/org/primefaces/examples/domain/?r=3692`. Any idea what I am missing here? Edit 1 I also downloaded PlayerConverter.java. Still same error.
