[klas]

When user is previewing uploaded file from form default content client is being used as it is missing in the link, resulting in non-authorized messages if field is not also added to the content tab of the type.

Hi Klas,
seem the "permission" issue is been solved, but it's running as "Download", while should work as "Preview" in a new window, as well as has been translated from Seblod team.
As Bes wrote here:

The download.php script is used to download...
To not download a PDF file but to open it into the web navigator, it's just to display a link to the physical PDF file. A typo plugin apply on value of file field can be a solution.
Of course, this usage is only for PUBLIC PDF file. By doing this there no ACL control of the file (done by the download.php script).
Here we are speaking about the Upload script, that by default from Seblod team show an icon link as "Preview", preview in a new window not download, or should be wrote "click to download" (at least this is what has been translated from Seblod team).

So the link shown after an upload by the Upload field, as far as I understand, is a "download link".
Considering that, when I upload a pdf, a checkbox is shown in case I want delete the file and upload a new one, Here should be tranformed by deafault:

• like a "A typo plugin apply on value of file field can be a solution"
• shown to the owner and hidden for all others users ("there no ACL control of the file (done by the download.php script)"
