Breaking: #88182 - jsfunc.inline.js has been dropped

Description

The JavaScript file jsfunc.inline.js which was responsible for FormEngine's subcomponent IRRE has been superseded by the rewritten \TYPO3\CMS\Backend\Form\Container\InlineControlContainer component.

Impact

Requesting the file typo3/sysext/backend/Resources/Public/JavaScript/jsfunc.inline.js will cause a 404 error. Calling any method of the global inline object will throw an error since the object doesn't exist anymore.

Affected Installations

All installations of TYPO3 are affected.

Migration

There is no migration available in most cases, since the \TYPO3\CMS\Backend\Form\Container\InlineControlContainer component is now event-driven.

One exception is the former inline.delayedImportElement() method, since this part is now based on postMessage. For this approach, a small helper utility TYPO3/CMS/Backend/Utility/MessageUtility has been added.

See the example for a possible migration:

// Previous code from DragUploader
window.inline.delayedImportElement(
    irre_object,
    'sys_file',
    file.uid,
    'file',
);

// New code
require(['TYPO3/CMS/Backend/Utility/MessageUtility'], function(MessageUtility) {
    const message = {
        objectGroup: irre_object,
        table: 'sys_file',
        uid: file.uid,
    };
    MessageUtility.send(message);
});

The MessageUtility.send() method automatically gets the current domain of the request and attaches it to the postMessage. MessageUtility.verifyOrigin() must be used to check whether the incoming request was sent by the current TYPO3 backend to avoid possible security issues.
