Hello, I'm in need of some assistance. I have a complex object hierarchy that I'm trying to create a JSF view for. I have simplified it to the point where I still get the error. Here is the setup:
Aobject that contains a list of Bobjects. Bobject contains an Eobject and then Eobject has a value attribute. Here is what I was trying to do in the jspx, note I am using Trinidad with facelets: <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page"; version="2.0" xmlns:ui="http://java.sun.com/jsf/facelets"; xmlns:h="http://java.sun.com/jsf/html"; xmlns:f="http://java.sun.com/jsf/core"; xmlns:tr="http://myfaces.apache.org/trinidad";> <ui:composition template="/view/template.jspx"> <ui:define name="content"> <h:form> <tr:panelHeader text="#{messages['com.eds.employeetracker.entity.admin.Aobject.search.he ader']}" messageType="none" /> <tr:panelHorizontalLayout halign="left"> <tr:panelFormLayout> <tr:panelBox background="transparent" inlineStyle="width: 100%;"> <tr:panelHeader text="#{messages['com.eds.employeetracker.entity.admin.Aobject.label']}" /> <tr:inputText label="#{messages['com.eds.employeetracker.entity.admin.Zobject.zvalue.l abel']}" value="#{manageAdminAobject.zvalue}" /> <tr:inputText label="#{messages['com.eds.employeetracker.entity.admin.Aobject.avalue.l abel']}" value="#{manageAdminAobject.avalue}" /> <tr:table id="bobjectListTable" value="#{manageAdminAobject.bobjectList}" var="bobjectList"> <tr:column headerText="#{messages['com.eds.employeetracker.entity.admin.Eobject.eva lue.label']}"> <tr:inputText label="#{messages['com.eds.employeetracker.entity.admin.Eobject.evalue.l abel']}" value="#{bobjectList.eobject.evalue}" /> </tr:column> </tr:table> <tr:panelButtonBar> <tr:commandButton text="#{messages['command.label.add']}" action="#{view$admin$aobjectManage.addAction}" /> </tr:panelButtonBar> </tr:panelBox> </tr:panelFormLayout> </tr:panelHorizontalLayout> </h:form> </ui:define> </ui:composition> </jsp:root> The page renders properly, however when I try to submit the page I get the following error: WARNING: executePhase(RENDER_RESPONSE 6,org.apache.myfaces.trinidadinternal.context.FacesContextFactoryImpl$Ca [EMAIL PROTECTED]) threw exception javax.el.ELException: /view/admin/aobjectManage.jspx @29,51 value="#{bobjectList.eobject.evalue}": Target Unreachable, 'eobject' returned null at org.apache.myfaces.trinidad.bean.ValueBindingValueExpression.isReadOnly( ValueBindingValueExpression.java:83) at org.apache.myfaces.trinidadinternal.renderkit.core.xhtml.EditableValueRe nderer.getReadOnly(EditableValueRenderer.java:244) at org.apache.myfaces.trinidadinternal.renderkit.core.xhtml.FormElementRend erer.renderAsElement(FormElementRenderer.java:217) at org.apache.myfaces.trinidadinternal.renderkit.core.xhtml.InputLabelAndMe ssageRenderer.getLabelFor(InputLabelAndMessageRenderer.java:78) at org.apache.myfaces.trinidadinternal.renderkit.core.xhtml.LabelAndMessage Renderer$Label.getForId(LabelAndMessageRenderer.java:617) at org.apache.myfaces.trinidadinternal.renderkit.core.xhtml.OutputLabelRend erer.encodeAll(OutputLabelRenderer.java:89) at org.apache.myfaces.trinidad.render.CoreRenderer.delegateRenderer(CoreRen derer.java:330) at org.apache.myfaces.trinidadinternal.renderkit.core.xhtml.LabelAndMessage Renderer.encodeAll(LabelAndMessageRenderer.java:193) at org.apache.myfaces.trinidadinternal.renderkit.core.xhtml.InputLabelAndMe ssageRenderer.encodeAll(InputLabelAndMessageRenderer.java:120) As stated the page does render fine as well as I do have the Aobject's list of Bobjects initilized, as well as the Bobject's Eobject is initialized if (manageAdminAobject.getId() == null) { manageAdminAobject.getBobjectList().add( new com.eds.employeetracker.entity.admin.Bobject()); manageAdminAobject.getBobjectList().get(0).setEobject( new com.eds.employeetracker.entity.admin.Eobject()); setManagedBean("manageAdminAobject", manageAdminAobject); } It seems that it doesn't handle a complex nested objects, as there are no issues with any non-complex value that is directly on the Bobject. Has anyone else seen this behavior and is there a way around it?? Any help would be greatly appreciated as, like most people, I'm under a huge time crunch to get the working. Thanks, Bob
