tom robert commentedAdded an extra to check to verify that the the remove button is clicked when setting the value to NULL.

nightlife2008 commentedThanks for the issue report and according patch.
I am not sure though if checking if a CSS class exists is the optimal approach to tackle this.
We should inspect the triggeringElement to see if we can derive the action from the #op property or something else.
I'm going into christmas holiday 'till the second of 2020 so this will be on hold until then.
Greets,

zanvidmar commentedSince 8.x-1.0-alpha7 this patch from #2 does not work anymore.
I created new patch that is checking the same thing (check to verify that the the remove button is clicked ) but I did it via trigger element last parent machine name which is in this case "remove_button".
Alternatively, it would be also possible to check the '#submit' value from trigger element to check if submission is related to "removeItem" method, but I am not sure if this has any advatages over what I wrote above.

bgreco commentedAfter upgrading from 1.0-alpha4 to 1.0-alpha7, I found that if the form element has a #default_value, the "Remove" button no longer works even in standard forms (I haven't tested an ajax form). The patch from #4 fixes this issue as well.

maskedjellybean#4 resolved the issue I was having after programmatically adding a Media Library field to the section configuration form of Layout Builder. I could add a media item but I couldn't remove it. After this patch I can add and remove.

nightlife2008 commentedI have merged the patch and created a new release: alpha8.
Thanks all!
