Attachment URL in the admin is not working.

[martinlagler]

The Attachment URL in the Data tab of the form is not correct.
Currently it's something like this
.../media/33/download/file
but instead of file it should be the filename and version.

[alexander-schranz]

The logic is currently placed here:

SuluFormBundle/ListBuilder/DynamicListBuilder.php

Lines 115 to 140 in b01a156

	private function getMediaUrl(string $value): string
	{
	return \str_replace('{id}', $value, $this->getDownloadUrl());
	}
	/**
	* For performance generate route only once.
	*/
	private function getDownloadUrl(): string
	{
	if (null === $this->downloadUrl) {
	// The given id must be a number which we replace
	$idReplacerNumber = '875421';
	$this->downloadUrl = \str_replace($idReplacerNumber, '{id}', $this->router->generate(
	'sulu_media.website.media.download',
	[
	'slug' => 'file',
	'id' => $idReplacerNumber,
	],
	RouterInterface::ABSOLUTE_URL
	));
	}
	return $this->downloadUrl;
	}

It would maybe be better to use the admin media redirect controller action instead of the direct download url.
