SAPUI5 and BPM: User authentification

Question

Hi there,
my UI5 application to claim and complete BPM tasks works now.
The only remaining issue I have is about user authentification.
To secure my UI5 application, I've modified web.xml and web-j2ee-engine.xml int the following way (according to this blog):
web.xml
<security-constraint>
     <web-resource-collection>
          <web-resource-name>ApproveRequest</web-resource-name>
          <url-pattern>/*</url-pattern>
     </web-resource-collection>
     <auth-constraint>
          <role-name>ApprovalWorkflow</role-name>
     </auth-constraint>
</security-constraint>
<login-config>
     <auth-method>FORM</auth-method>
     <realm-name>ApprovalWorkflow</realm-name>
</login-config>
<security-role>
     <role-name>ApprovalWorkflow</role-name>
</security-role>
web-j2ee-engine.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-j2ee-engine xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:noNamespaceSchemaLocation="web-j2ee-engine.xsd">
     <spec-version>2.4</spec-version>
     <security-role-map>
     <role-name>ApprovalWorkflow</role-name>
     <server-role-name>Administrator</server-role-name>
     </security-role-map>
</web-j2ee-engine>
My user is coming from Active Directory and assigned to the UME role "Administrator".
If I open my UI5 application, the standard SAP login form is displayed.
But after successful login my application fails when the oData model is created:
var oDataModel = new sap.ui.model.odata.ODataModel(taskDataSvcURL, true);
In the debugger I get the following error message (and nothing in NWA logs):
Uncaught TypeError: Cannot read property 'dataServices' of undefined
If I'm logged into to some SAP standard application (NWA, Portal) before calling my application, everything's working fine.
Thanks in advance.
Best regards,
Thorsten.

Hi,
I solved it myself with the help of our basic admin.
Go to "NWA->Configuration->Security->Authentification and Single Sign-On".
Then select "SAP-J2EE-Engine" and click on "Edit".
Search you SAPUI5 application and set "Used Template" to "Ticket"
Afterwards it works for me.
