YOu are missing the sharing reference in your portalapp.xml. take a look at the following portalapp.xml
and add <b>com.sap.portal.ivs.connectorservice</b> as sharing reference.
<?xml version="1.0" encoding="utf-8"?>
<application>
  <application-config>
    <property name="PrivateSharingReference" value="com.sap.portal.htmlb,com.sap.portal.ivs.connectorservice"/>
  </application-config>
  <components>
    <component name="display">
      <component-config>
        <property name="ClassName" value="com.ust.bwextract.display"/>
        <property name="SecurityZone" value="com.ust.bwextract/high_safety"/>
      </component-config>
      <component-profile>
        <property name="System Alias" value="BWDEV"/>
      </component-profile>
    </component>
  </components>
  <services/>
</application>
PS: Thanks for the points if it works out. thank you.
