Are you referring to the x icon?

For more context I believe you are referring to the following situation:

- Source = BLOB Column… 
- In combination with Form - Automatic Row Processing.

And not Table APEX_APPLICATION_TEMP_FILES. Because with the latter it requires your own processing, which you would do you own file handling.

This may be considered a potential bug, as the x should clear the blob column.

Hi, 

Yes, thats correct, the x-icon.

Indeed not the table APEX_APPLICATION_TEMP_FILES from wwv_flows_files.

Hi,

I have exactly the same problem.

So, is it a bug? fix/workround? I am on APEX 23.2.1.

Hi,

I am experiencing the same issue. When will this be resolved?

Eventually. It is marked as a low priority.

I was able to address this problem creating a computation on the upload image item

On the computation,

I put server-side condition as: when my upload image is null 

then

on the computation tab 

static value = null

Thanks! Please note that the computation execution must be Point: After Submit

If you use the image upload item in 24.2 as an Icon Dropzone with own BLOB storage, there is an error setting a tabindex attribute on the remove icon. In 24.2, is seems there has been made an effort of disabling the remove icon.

So, for what it's worth, I have made a workaround in JavaScript.

• Add a Custom Attribute in the advanced section of the Image Upload item on your page. This wil show/hide the icon when needed.

show-clear-button="true"

• Add my Javascript code to the global JavaScript file, or just load it on the page. It will add a click handler to the DOM. When the remove icon is clicked, a dummy empty file will be created and enqueued to the input files list.
  There is a timeout because there is another event on the same DOM element, this event changes the DOM to make it look like there is no file AND it cleares the input files list.

let $fileUpload = $('a-file-upload[show-clear-button]');
$fileUpload.each((index, element) => {
    $fileUpload.on("click", (event) => {
        if (event.target.closest('.a-FileDrop-remove')) {
            event.preventDefault();
            setTimeout(() => {
                dataTransfer = new DataTransfer();
                file = new File([], 'no_file');
                dataTransfer.items.add(file);
                element._wrappedElement$[0].files = dataTransfer.files;
            }, 50);
        }
    });
});

Hope this helps!

Another thing that would be very useful is to allow/disallow users to remove the BLOB file, maybe with a authorizathion scheme… it is so simple and it would help a lot

@alan arentsen Thank you, works like a charm

@yuri.kfreitas can you use the read only attribute on the item?
