Filter uploaded files from hasUploads if ERR_NO_FILE detected

[thojou]

As outlined in https://mantis.ilias.de/view.php?id=42106, we encountered an issue with file upload handling in the assFileUpload component. Specifically, when a form with a file upload field is submitted without selecting a file, it results in an empty UploadedFile object. Below is a sample dump illustrating the issue:

The problem arises because the hasUploads method still returns true, as it counts any available entries from the HTTP request, regardless of whether a file was actually uploaded.

We modified the hasUploads method to filter out files with the error "ERR_NO_FILE", ensuring that they are not counted as valid uploads.

If this change is likely to introduce side effects—for example, if the method is expected to return all files, regardless of their error state—an alternative solution could be to implement a custom hasValidUploads method. This would specifically count only successfully uploaded files.

Hi @chfsx, any updates on this PR? I ask in my role as authority for T&A, the Mantis issue 42106 was first assigned to me. As the end of full support for ILIAS 8 is near, would it be possible to merge this PR or needs the PR some changes from @thojou?

Thanks and best regards

Hi @chfsx
I don't know if this is needed and correct. At least in the test I think the current behavior without the changes is correct and the issue in the test needed a different fix.

Best,
