<p>I'm using primefaces 2.2.1 with JSF 2.0. I have a page with various labels to display data, some listboxes and a couple of commandButtons. No matter what I do, whenever I click on a command button in this page, I get the following error:</p> <pre><code>java.lang.NullPointerException at org.primefaces.component.inputmask.InputMaskRenderer.getConvertedValue(InputMaskRenderer.java:115) at javax.faces.component.UIInput.getConvertedValue(UIInput.java:1030) at javax.faces.component.UIInput.validate(UIInput.java:960) at javax.faces.component.UIInput.executeValidate(UIInput.java:1233) at javax.faces.component.UIInput.processValidators(UIInput.java:698) at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1214) at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1214) at javax.faces.component.UIForm.processValidators(UIForm.java:253) at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1214) at javax.faces.component.UIComponentBase.processValidators(UIComponentBase.java:1214) at javax.faces.component.UIViewRoot.processValidators(UIViewRoot.java:1172) at com.sun.faces.lifecycle.ProcessValidationsPhase.execute(ProcessValidationsPhase.java:76) at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:101) at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:118) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:409) at org.apache.catalina.core.StandardWrapper.service(StandardWrapper.java:1534) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:343) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:215) at org.primefaces.webapp.filter.FileUploadFilter.doFilter(FileUploadFilter.java:79) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:256) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:215) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:279) 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 com.sun.enterprise.web.WebPipeline.invoke(WebPipeline.java:98) at com.sun.enterprise.web.PESessionLockingStandardPipeline.invoke(PESessionLockingStandardPipeline.java:91) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:162) at org.apache.catalina.connector.CoyoteAdapter.doService(CoyoteAdapter.java:326) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:227) at com.sun.enterprise.v3.services.impl.ContainerMapper.service(ContainerMapper.java:170) at com.sun.grizzly.http.ProcessorTask.invokeAdapter(ProcessorTask.java:822) at com.sun.grizzly.http.ProcessorTask.doProcess(ProcessorTask.java:719) at com.sun.grizzly.http.ProcessorTask.process(ProcessorTask.java:1013) at com.sun.grizzly.http.DefaultProtocolFilter.execute(DefaultProtocolFilter.java:225) 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:619) </code></pre> <p>I have no idea why. Anyone has an idea of what might be causing this? I am also using entity classes and a managed bean for this page. This is part of the JSF Page: The error occurs whenever a command button is clicked.</p> <pre><code><?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/ xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:p="http://primefaces.prime.com.tr/ui" xmlns:ui="http://java.sun.com/jsf/facelets"> <f:view> <h:head> <link rel="stylesheet" type="text/css" href="../resources/css/masterpage.css" /> <link rel="stylesheet" type="text/css" href="../resources/css/requests.css" /> </h:head> <h:body> <h:form prependId="false" > <p:growl id="messages" showDetail="true"/> <p:panel id="pnlMain" widgetVar="pnlMain" style="width: 100%; font-size: 15px; text-align: left" header="Request Detail"> . . . <table> <tr> <td valign="top"> </td> <td align="right"> <p:commandButton id="btnViewComment" widgetVar="btnViewComment" ajax="false" value="View Selected" /> </td> <td> </td> </tr> </table> <p:panel id="pnlSupportingDocs" widgetVar="pnlSupportingDocs" header="Supporting Documents" > <div> <table> <tr> <td valign="top" > <h:selectOneListbox id="lstDocs" style="width: 300px; height: 100px" value="#{MyDocuments.doId}" > <f:selectItems value="#{RequestSearch.selectedRequest.documentCollection}" var="d" itemLabel="#{d.doName}" itemValue="#{d.doId}" /> </h:selectOneListbox> </td> <td valign="bottom" > <table> <tr> <td> <p:commandButton id="btnViewSelected" style="font-size: 8px; width: 150px" widgetVar="btnViewSelected" value="View Selected" /> </td> </tr> <tr> <td> <p:commandButton id="btnRemoveSelected" style="font-size: 8px; width: 150px" widgetVar="btnRemoveSelected" value="Remove Selected" /> </td> </tr> <tr> <td> <p:fileUpload id="btnNewDoc" widgetVar="btnNewDoc" update="messages" allowTypes="*.*" description="All Files" fileUploadListener="#{MyDocuments.handleFileUpload}" /> </td> </tr> </table> </td> </tr> </table> </div> </p:panel> <p:panel id="pnlFinalization" widgetVar="pnlFinalization" header="Final Evaluation" > <table> <tr> <td valign="top" > <h:outputLabel id="lblComments" style="font-size: 12px" value="Comments:" /> </td> <td> <p:inputTextarea id="txtComments" widgetVar="txtComments" style="width: 300px" maxHeight="600" /> </td> </tr> </table> <table> <tr> <td> <h:outputLabel id="lblFinalAdjAmt" style="font-size: 12px" value="Final Adjustment Amt:" /> </td> <td> <p:inputMask id="txtFinalAdjAmt" widgetVar="txtFinalAdjAmt" mask="$9999999.99" style="width: 100px; text-align: right" maxlength="15" /> </td> <td width="100px" > </td> <td> <h:outputLabel id="lblFinalStatus" style="font-size: 12px" value="Final Status:" /> </td> <td> <h:selectOneMenu id="cmbStatus" value="#{theStatus.reqStatus}" > <f:selectItems value="#{theStatus.finalStatus}" /> </h:selectOneMenu> </td> <td> <p:commandButton id="btnSave" widgetVar="btnSave" value="Save" /> </td> </tr> </table> </p:panel> </p:panel> <p:dialog header="Print Forms" id="pf" widgetVar="pf" modal="true" width="450" height="300"> <iframe src="../PopUpPages/FormMenu.jsf" width="400" height="250" /> </p:dialog> <p:dialog header="Comment Detail" id="cd" widgetVar="cd" modal="true" width="450" height="300" > </p:dialog> <p:dialog header="Supporting Documents" id="sd" widgetVar="sd" modal="true" width="600" height="800" > <iframe src="../PopUpPages/SupportingDoc.jsf" width="590" height="650" scrolling="true" /> </p:dialog> </h:form> </h:body> </f:view> </html> </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
