I am trying to figure how this seam entity bean validation and form validation fit together. Here are a couple questions: 1. Are the @NotNull validation annotations and the validation attributes like 'required="true" mutually exclusive? In other words, can I only use one or the other? 2. What mechanism in seam causes the form to be re-displayed instead of the seam debug page when there are Hibernate validation errors? (Particularily when the EntityHome.persist() method is called) A little background on question 2: When my application was first created using seam-gen, when fields on the form were invalid, the form would be redisplayed and the entity would not be persisted to the database. Since then I have made many changes, and now it appears that when the form is submitted that my EntityHome object tries to persist the object instance whether the form is valid or not. If I remove the hibernate validation annotations from the Entity Bean, then the object is persisted to the DB even if the fields violate the "requrired=true" attrubute in the form fields. But if I keep the hibernate validation annotations in the entity bean, the Seam debug page is displayed instead of the form and error messages. The debug page stack trace contains this error message: org.hibernate.PropertyValueException: not-null property references a null or transient value Here is my form page: | <!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" | "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> | | <ui:composition xmlns="http://www.w3.org/1999/xhtml" | xmlns:s="http://jboss.com/products/seam/taglib" | xmlns:ui="http://java.sun.com/jsf/facelets" | xmlns:f="http://java.sun.com/jsf/core" | xmlns:h="http://java.sun.com/jsf/html" | xmlns:a="https://ajax4jsf.dev.java.net/ajax" | xmlns:rich="http://richfaces.ajax4jsf.org/rich" | template="layout/frametemplate.xhtml"> | | <style> | .gridContent { | vertical-align:top; | } | | .outpanelHeader { | height:4px; | border-width: 0; | } | .inpanelBody { | height:580px; | overflow:auto; | } | | </style> | <ui:define name="body"> | <h:messages globalOnly="true" styleClass="message" id="globalMessages" /> | | <h:form id="rptprdmgbinder" styleClass="edit"> | | <h:inputHidden id="clientaddress" | value="#{rptprdmgbinderHome.instance.clientaddress}"> | </h:inputHidden> | | <h:inputHidden id="lienaddress" | value="#{rptprdmgbinderHome.instance.lienaddress}"> | </h:inputHidden> | | <rich:panel> | <f:facet name="header">Edit Property Damage Binder</f:facet> | | <h:inputHidden id="lineOfBusiness" | value="#{rptprdmgbinderHome.instance.lineOfBusiness}"> | </h:inputHidden> | | <h:inputHidden id="id" | value="#{rptprdmgbinderHome.instance.id}"> | </h:inputHidden> | | | <!-- </rich:panel>--> | | <!-- <rich:panel>--> | <!-- <f:facet name="header">Client</f:facet>--> | <h:panelGroup> | <h:panelGrid columns="2" style="width:100%" columnClasses="list2, list2"> | <s:decorate id="clientname1Decoration" | template="layout/edit.xhtml"> | <ui:define name="label">Client Name 1</ui:define> | <s:validateAll> | <h:inputText id="clientNameLine1" size="40" maxlength="50" | styleClass="list2" required="true" | value="#{rptprdmgbinderHome.instance.clientNameLine1}"> | | </h:inputText> | </s:validateAll> | </s:decorate> | </h:panelGrid> | | | </h:panelGroup> | | | | <h:inputHidden id="policyid" | value="#{rptprdmgbinderHome.instance.policyid}"> | </h:inputHidden> | | <h:inputHidden id="companyname" | value="#{rptprdmgbinderHome.instance.company}"> | </h:inputHidden> | | <div style="clear:both"> | <span class="required">*</span>required fields | </div> | | <div class="actionButtons"> | <s:button action="#{rptprdmgbinderHome.persist}" id="save" | value="Save" disabled="#{!rptprdmgbinderHome.wired}" | rendered="#{!rptprdmgbinderHome.managed}"> | <f:param name="rptprdmgbinderFrom" value="#{rptprdmgbinderFrom}" /> | </s:button> | | <h:commandButton id="update" value="Save" | action="#{rptprdmgbinderHome.update}" | rendered="#{rptprdmgbinderHome.managed}" /> | | <s:button action="#{rptprdmgbinderHome.remove}" id="delete" | value="Delete" rendered="#{rptprdmgbinderHome.managed}"> | <f:param name="rptprdmgbinderFrom" value="#{rptprdmgbinderFrom}" /> | </s:button> | | <s:button id="done" value="Done" propagation="end" | view="/Rptprdmgbinder.xhtml" | rendered="#{rptprdmgbinderHome.managed}" /> | | <s:button id="cancel" value="Cancel" propagation="end" | view="/#{empty rptprdmgbinderFrom ?
