EDIT

The code which configures the error hanlder should also go into the abstract base class:

        DelegatingErrorHandler delegatingErrorHander = new DelegatingErrorHandler();
        WindowErrorHandler errorHandler = new WindowErrorHandler(this, RegistrationUIDefaults.ERROR_CONTACT_MESSAGE_LINE + "</br></br>"
                + "<i>To help analyzing the problem please describe your actions that lead to this error and provide the error details from below in your email. "
                + "You also might want to add a sreenshot of the browser page in error.</i>");
        delegatingErrorHander.registerHandler(new ErrorTypeErrorHandlerWrapper<PermissionDeniedException>(PermissionDeniedException.class, new PermissionDeniedErrorHandler(this)));
        delegatingErrorHander.registerHandler(new ErrorTypeErrorHandlerWrapper<Exception>(Exception.class, errorHandler));
        setErrorHandler(delegatingErrorHander);
        VaadinSession.getCurrent().setErrorHandler(delegatingErrorHander);

also other code part of the init method

To be implemented for

• DistributionStatusUI URGENT: this UI is already based on the UI interface only
• StatusEditorUI: still based on the AbstractAuthenticatedUI
• ConceptRelationshipUI: still based on the AbstractAuthenticatedUI

Additional

• drop AbstractAuthenticatedUI and CdmBaseUI once done
