Page Indexer: Bug during File Reference Indexing

[cepheiVV]

The method getPageContent() in class /Classes/Indexer/Types/Page.php loads FileReferences and Links within a foreach loop into a variable $fileObjects.

If your Indexer configuration contains multiple RTE field, e.g:

The foreach loop will override the $fileObjects variable, thus only the links of last RTE field will be indexed.

// index content of this content element and find attached or linked files.
// Attached files are saved as file references, the RTE links directly to
// a file, thus we get file objects.
// Files go into the index no matter if "index_content_with_restrictions" is set
// or not, that means even if protected content elements do not go into the index,
// files do. Since each file gets its own index entry with correct access
// restrictions, that's no problem from an access permission perspective (in fact, it's a feature).
foreach ($contentFields as $field) {
    $fileObjects = array_merge(
        $this->findAttachedFiles($ttContentRow),
        $this->findLinkedFilesInRte($ttContentRow, $field)
    );

    $content .= $this->getContentFromContentElement($ttContentRow, $field) . "\n";
}

// index the files found
if (!$pageAccessRestrictions['hidden']
    && $this->checkIfpageShouldBeIndexed($uid, $this->pageRecords[(int)$uid]['sys_language_uid'])
    && !empty($fileObjects)
) {
    $this->indexFiles($fileObjects, $ttContentRow, $pageAccessRestrictions['fe_group'], $tags);
}

In this example configuration, when $this->indexFiles() is executed, the variable $fileObjects will be empty, even if the RTE field bodytext contains links.
