No authentication result builder can be located in the context -> upgrade problem from 4.2.7 to 5.1.3

[Priit Serk]

Hi

I need to upgrade working solution from cas 4.2.7 to latest. 4.2.7 solution is working perfectly but the latest 5.1.3 is a bit different and I cant get it to work - desperate already :(

Exception:
2017-09-08 00:56:18,748 WARN [org.apereo.cas.web.flow.resolver.impl.InitialAuthenticationAttemptWebflowEventResolver] - <No authentication result builder can be located in the context>

java.lang.IllegalArgumentException: No authentication result builder can be located in the context

Custom web-flow:

<var name="loginModel" class="ee.LoginModel"/>

<view-state id="viewLoginForm" view="casLoginView" model="loginModel">
   <binder>
      <binding property="username"/>
      <binding property="password"/>
      <binding property="mobileNumber"/>
      <binding property="personalCode"/>
   </binder>
   <on-entry>
      <set name="viewScope.commandName" value="'loginModel'"/>
   </on-entry>
   <transition on="startMIDLogin" to="mIDLoginStart" bind="true" validate="false"/>
</view-state>

<action-state id="mIDLoginStart">
   <evaluate expression="mobileIDLoginAction.submit(flowRequestContext, flowScope.loginModel.getMobileNumber())"/>
   <transition on="success" to="viewMobileIDLoginCode"/>
   <transition on="error" to="viewLoginError"/>
</action-state>

<view-state id="viewMobileIDLoginCode" view="casMIDLoginCode">
   <transition on="check" to="checkMIDStatus"/>
</view-state>

<action-state id="checkMIDStatus">
   <evaluate expression="mobileIDLoginAction.check(flowRequestContext)"/>
   <transition on="success" to="credentialsSuccess"/>
   <transition on="outstanding" to="viewMobileIDLoginCode"/>
   <transition on="error" to="viewLoginError"/>
</action-state>

<action-state id="credentialsSuccess">
   <!-- This is how it's defined in cas 4.2.7 - unfortunately this does not work anymore in 5.1.3
      <evaluate expression="authenticationViaFormAction.submit(flowRequestContext, flowScope.IDCredential, messageContext)"/>
   -->
   <evaluate expression="authenticationViaFormAction"/>  <!-- THIS RAISES THE ERROR -->

   <transition on="warn" to="warn"/>

   <transition on="success" to="sendTicketGrantingTicket"/>
   <transition on="authenticationFailure" to="handleAuthenticationFailure"/>
   <transition on="error" to="initializeLoginForm"/>
</action-state>


As you can see from the comment, the line:

   <evaluate expression="authenticationViaFormAction"/> raises the exception. 

I'm pasting also other code:

@Component("mobileIDLoginAction")
public class MobileIDLoginAction {

@PostConstruct
public void init() {
 ....
}

public Event check(RequestContext context) {
   MobileIDSession session = (MobileIDSession) context.getFlowScope().get(MOBILE_SESSION);
   int checkCount = (int) context.getFlowScope().get(AUTH_COUNT);
...
}


public Event submit(RequestContext context, String mobileNumber) {
   try {
      MobileIDSession mIDSession = mIDAuthenticator.startLogin(mobileNumber);
....
}

public class IDCredential extends AbstractCredential {

   private String firstName;
   private String lastName;
   private String identityCode;
   private String phoneNumber;
....
}

public class LoginModel implements Serializable {

   private String mobileNumber;
   private String personalCode;
   private String country;
   private String username;
   private String password;
...
}


Exception:

java.lang.IllegalArgumentException: No authentication result builder can be located in the context

Everything works inside MobileIDLoginAction and I just to accept authentication and that's it. 

Please help, I'm really in trouble and no idea how to continue at this point.
