Save draft blocked by file upload control

Question

Hi,
I am using 'Save draft' functionality on a User task.
The user task interface has an editable grid, containing file upload control in each row. The row can be dynamically added or deleted (using the X icon implemented in the top right column - dynamicLink).

As explained in https://community.appian.com/support/w/kb/802/kb-1480-unable-to-save-changes-on-a-sail-form-if-an-file-upload-component-is-present-with-uploaded-files 'Save Draft' functionality doesn't work with files temporary uploaded to the form and I have to live without it [emoticon:c4563cd7d5574777a71c318021cbbcc8]
However,
I have a problem if users uploads a file in a grid row and deletes the row (clearing the grid row item in a grid data source and clearing the save target of the fileupload component contained in the grid row). I am not able to clear the inactive temporary saved file from the memory and Appian keeps preventing the Save draft as the fileupload is still there, although fileupload component is not present in the form.
I am still getting the following error:

Is there any function available that can be used to clear the inactive temp file from the form on a grid row deletion?

That's a known limitation. I suggest to not use the red X to remove rows, but the normal document upload button functionality.

My normal trick is to do a row-by-row detection for whether there's a newly-uploaded file in that row of the grid, and if so, disable the "remove row" icon (and provide mouseover text that explains that the user must clear out the newly-uploaded file prior to removing the row).
