Bug #77972
Updated by Hendrik Putzek over 7 years ago
If a backend field for inserting an image is configured like
<pre>
<maxitems>1</maxitems>
<minitems>1</minitems>
</pre>
the button to add a new relation is hidden by inline style "display:none". (Which is correct)
But if the image is deleted by using the trashcan icon, the upload button does not show up again.
This leads to the following behaviour:
* Its not possible to save the form (validation says there must be at least one image)
* Its not possible to add another image and therefore make the form valid because of the missing upload button
The Buttons are hidden in typo3/sysext/backend/Classes/Form/Container/InlineControlContainer.php:247
In https://forge.typo3.org/issues/45125 is stated that:
"The buttons are not immediately
hidden/shown if the number of relation changes. That would involve
JavaScript magic and could be done in a follow up."
That Javascript seems to be not implemented yet.

Steps to reproduce:
* Create a flexform including an inline field for inserting an image.
Set
<pre>
<maxitems>1</maxitems>
<minitems>1</minitems>
</pre>
* Upload one image and save the form
* The upload button is hidden
* Delete the uploaded image using the trashcan icon
* *The upload button does not show up again*
