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

See [forge#88182](https://forge.typo3.org/issues/88182)

## 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superseded by the rewritten `\TYPO3\CMS\Backend\Form\Container\InlineControlContainer` component.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:

```javascript
// 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.
