Class 'InstituteWeb\Unroll\Xclass\UnrolledSplitButton' not found

[Former user]

After installing this extension under TYPO3 8.7.7 using composer, I get this error message:

Class 'InstituteWeb\Unroll\Xclass\UnrolledSplitButton' not found

I double checked all class pathes for wrong spelling or case, do "composer dumpautoload", cleared all known caches, but no changes.

I use composer since the beginning, and had never a problem like this. All other extensions (of course, also installed by composer) are working.

I work under macOS, but my development system runs inside docker under ubuntu 16.04.

The error message appears after trying to open a content element.

I get the same error, maybe this is a caching-problem of packagist (is this possible?)? strange.

• On a FRESH 8.7.8 composer-install (new server, too) I added the following line to required-section
• "instituteweb/unroll": "^2.0"
• shell "./composer.phar update"
• Extension is loaded, everything looks fine
• packagestates are created by typo3-console --> @php vendor/helhum/typo3-console/Scripts/typo3cms install:generatepackagestates

But then I try to add a new Content-Element (Wizard opens), after clicking a CE-Icon in the wizard I get the error.

Class 'InstituteWeb\Unroll\Xclass\UnrolledSplitButton' not found

The strange thing is that I get wrong paths in the autoload files:

vendor/composer/autoload_psr4.php

    'InstituteWeb\\Unroll\\' => array($baseDir . '/web/typo3conf/ext/rx_unrollsavebuttons/Classes'),

/vendor/composer/autoload_static.php

    'InstituteWeb\\Unroll\\' =>
        array (
            0 => __DIR__ . '/../..' . '/web/typo3conf/ext/rx_unrollsavebuttons/Classes',
    ),

I also tried a grep in typo3conf/ext/unroll for "rx_unrollsavebuttons", but only found the following entries (no problem here):

unroll/composer.json

    "replace": {
                "unroll": "self.version",
                "typo3-ter/unroll": "self.version",
                "rx_unrollsavebuttons": "*",
                "reelworx/rx-unrollsavebuttons": "*"
        },

unroll/ext_emconf.php

    'conflicts' => [
            'rx_unrollsavebuttons' => '1.0.0-1.99.99',
        ],

after I corrected the path MANUALLY, everything worked fine.

vendor/composer/autoload_psr4.php

    'InstituteWeb\\Unroll\\' => array($baseDir . '/web/typo3conf/ext/unroll/Classes'),

/vendor/composer/autoload_static.php

    'InstituteWeb\\Unroll\\' =>
        array (
            0 => __DIR__ . '/../..' . '/web/typo3conf/ext/unroll/Classes',
    ),
