CAP Fiori Elements warnings on READ requests

[a_oezsoy]

Hi,

I am working on a CAP project with Fiori Elements List Report frontend. I have a custom on READ handler for a certain entity and I would like to show notifications to the user on the UI after the read event.

The way I implemented it is as follows:

service.js
----------------
module.exports = (srv) => {
    // ...
    srv.on('READ', 'Connections', (req) => {
        // ...
        if (...) {
            req.warn({code: 'DATA_INCOMPLETE',message: 'Data could only be partially retrieved. ...'});
        }
        // ...
    });
    // ...
}

The request functions with lower severities (warn/info/notify) don't seem work when I am handling READ requests.

Is this normal behaviour? If so, is there another "CAP/Fiori Elements way" of showing the warnings to the user (other than writing it in native UI5)?

Thanks,

Atakan
