    Validation with pageflows

    Daniel Spangler Newbie

      How do you get a pageflow to stay on the same page if a validation error occurs?

      I am currently using the s:validateAll tag to initiate the validation within my page. I have an h:commandButton that triggers the transition change. I can see DEBUG statements from the ValidationInterceptor stating that a validation error has occurred, but the page continues to go to the next transition. I have tried adding @IfInvalid(outcome=Outcome.REDISPLAY) to my action but that doesn't seem to do anything.

      Any help would be greatly appreciated.

          If validation is failing you shouldn't reach the action method.

          Post some code!

            Here is some code:

            The beans:

            @Entity
            @Name("payment")
            @Scope(ScopeType.CONVERSATION)
            public class PaymentBean implements Payment {
            
             @NotNull
             @Length(max=12,min=10)
             @Pattern(regex="^[a-zA-Z0-9]+$", message="Must be alphanumeric.")
             private String accountNumber;
            
             public String getAccountNumber() {
             return accountNumber;
             }
            
             public void setAccountNumber(final String accountNumber) {
             System.out.println("Setting accountNumber to: " + accountNumber);
             this.accountNumber = accountNumber;
             }
            
             @Begin(join=true)
             public void begin()
             {
             System.out.println("PaymentBean.begin()");
             }
            
            }
            
            @Name("paymentAction")
            @Stateful
            @Scope(ScopeType.CONVERSATION)
            public class PaymentActionBean implements PaymentAction {
            
             @In(create=true)
             @Valid
             private Payment payment;
            
             @Create @Begin(join=true)
             public void begin()
             {
             System.out.println("PaymentActionBean.begin()");
             }
            
             @Remove
             @Destroy
             public void destroy() {
             System.out.println("PaymentActionBean.destroy()");
             }
            
             @IfInvalid(outcome = Outcome.REDISPLAY)
             public void doAuthenticate()
             {
             System.out.println(payment.getAccountNumber());
             System.out.println("I am authenticating");
             }
            
             ...
            }
            
            


            Here is the flow:
            <pageflow-definition name="payment-flow">
            
             <start-page name="authenticate" view-id="/authenticate.jspx">
             <redirect/>
             <transition to="authenticate">
             </transition>
             <transition name="doAuthenticate" to="confirm">
             <action expression="#{paymentAction.doAuthenticate}"/>
             </transition>
             </start-page>
            
             <page name="confirm" view-id="/confirm.jspx">
             <redirect/>
             <transition name="doConfirm" to="transact">
             <action expression="#{paymentAction.doConfirm}"/>
             </transition>
             </page>
            
             <decision name="transact" expression="#{true}">
             <transition name="true" to="acknowledge">
             <action expression="#{paymentAction.doTransact}"/>
             </transition>
             </decision>
            
             <page name="acknowledge" view-id="/acknowledge.jspx">
             <redirect/>
             <end-conversation/>
             </page>
            
            </pageflow-definition>
            


            And finally the first page:
            <?xml version="1.0"?>
            <jsp:root xmlns:jsp="http://java.sun.com/JSP/Page"
             xmlns:h="http://java.sun.com/jsf/html"
             xmlns:f="http://java.sun.com/jsf/core"
             xmlns:s="http://jboss.com/products/seam/taglib"
             xmlns="http://www.w3.org/1999/xhtml"
             version="2.0">
             <jsp:output doctype-root-element="html"
             doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN"
             doctype-system="http://www.w3c.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"/>
             <jsp:directive.page contentType="text/html"/>
             <head>
             <title>Authenticate...</title>
             </head>
             <body>
             <h1>Authenticate...</h1>
             <f:view>
             <h:form>
             <h:messages globalOnly="true"/>
             <h:outputText value="Enter Account Number:"/>
             <h:inputText value="#{payment.accountNumber}" id="accountNumber" required="true">
             </h:inputText>
             <s:validateAll/>
             <h:commandButton value="Ok" action="doAuthenticate"/>
             <br/>
             </h:form>
             </f:view>
             </body>
            </jsp:root>
            
            


            I see this in the log file but the flow continues to the next page. How can I make it stay on the first page?

            2007-01-23 09:23:31,296 DEBUG [org.jboss.seam.interceptors.ValidationInterceptor] invalid value: accountNumber length must be between 10 and 12
            2007-01-23 09:23:31,296 DEBUG [org.jboss.seam.interceptors.ValidationInterceptor] invalid value: accountNumber Must be alphanumeric.


            Thanks in advance,

              I figured out what the problem was. I wasn't surrounding the h:inputText tag with the s:validateAll tag.
