File Upload validation message

Unfortunately I believe the only way to clear it out is to exit / reopen the task, or to hard refresh it (i.e. a browser refresh).

Thanks Stefan/Mike for replying. We don't expect it to happen often but business wanted to know if there is a way in which we can clear it out.

This is a variation of the same known issue - this has been posted about before. I believe bug reports have been sent to Appian but I don't know if/when they plan to address it. As Stefan mentioned - is this actually happening very often? The only real suggestion I have is user education.

I do not know of a way to do that. But, does that happen a lot in real life?

One option might be to dynamically create a new file upload field.

Hi,

We are facing this challenge in an assigned task. The system-level validation does not get cleared when a valid file gets uploaded. Is there a way in which we can clear up these validations?

Steps:
Uploaded a blank file and got the below validation.
Uploaded a valid file but the earlier validation does not get cleared.

I believe this relates to a long-standing known issue with the system-level validation message that fires when such a document is uploaded. For instance in my system we disallow the ".heic" extension to prevent space wastage, and (in interface designer) the validation message fails to clear even if I replace it with a completely valid file. As OP noted though, this doesn't appear to be happening in actual tasks, just in the designer.

a!localVariables(
  
  local!doc,
  
  a!fileUploadField(
    value: local!doc,
    saveInto: local!doc,
    maxSelections: 1
  )
)

Step 1: upload file with disallowed extension
Step 2: try doing literally anything else

Could you please share the code snippet of how you are evaluating the validation and also let us know if you are uploading multiple files to check at once or single file at a time and evaluating, for our better understanding.

That glitch only happens in the interface designer, not when the interface is used in an assigned task.

OK. This "after that", what exactly is that?

The reason I ask is that when you try to set the variable value to NULL from external, then the internal state of that field does not get updated correctly. That is a known issue. If you use the control inside the file upload field, this should work.

1. I am trying to upload an invalid file, such as a .sql file.
2. I get the error message mentioned above.
3. After that, I try uploading a valid .pdf file, but the above validation message still appears.
4. When I upload a valid file, the validation message should not appear, but it still shows up when I try to upload a valid one.

What are the EXACT steps you do to make this happen?
