Deleting File from fileupload field on edit leads to error

[ontarget]

Using J4.2.6 Fabrik Beta4B
Fileupload element / ajax upload = yes
Validation = notempty on Both

Multigroup form with pagination

When I create a new form entry the validation check on the fileupload fields works and I cannot proceed to the next page in the form without uploading a file.

When I edit the same form record and delete the file via the ajax uploader X icon next to the element, I can continue through the pagination and submit the form even though the fileupload field has a validation of notempty on Both (New and Edit) - Any ideas why it's not validating on Edit?
Also after the form submission if I try to edit the same form record again I get the following error:

count(): Argument #1 ($value) must be of type Countable|array, string given

I'm wondering if this is a simple element setting I'm missing?

There are still issues with the fileupload.
But

• Fabrik 4.0Gamma is out
• Error: Can you enable Joomla's System Debug to get an error stack?
• There is a critical security issue with J! <4.2.8, you should update

Is this behaviour different from Fabrik 3?

@troester thank you as always for the fast response.
I will complete those updates.
Sorry IDK with F3 if this is the same.
When looking at the db entry for a file upload it goes from a populated array to an empty array when deleted using the ajax upload element

[{"file":"\/images\/uploads\/1003\/somefile.pdf","params":"{}"}]

to

[]

This would probably explain the count error - I would suggest the delete action would set a Null value instead if that's possible?
It might also fix the validation because technically an empty list is not notempty!

So you have ajax upload = yes and max files = 1?

Yes that is correct - is there another setting I should try?
