[TYPO3-core] RFC #16006: Feature - Remove the checkbox that clears the input fields in TCE-forms and replace it with a sprite icon

[Alexander Stehlik]

Hi,

I just stumbled upon this because the documentation for this new 
behaviour is missing.

In TYPO3 4.4 the checkbox did not only clear the field but there was 
also the possibility to set the value that was stored in the database if 
the field was not checked.

So for example: When I have a title field and set
checkox => 'no title'
and the checkbox is not checked "no title" will be stored in the database.

I don't really miss this feature but the documentation should be 
updated, that checkbox will only render a clear button since 4.5.

Another thing I noticed: There is a bug in this patch that makes the 
checkbox option completely obsolete:

if (isset($config['checkbox'])) {
...
}

This check is always true because if "checkbox" was not set in the 
configuration it is defaulted to an empty string or "0". The result ist, 
that the clear button is shown in all input fields no matter if checkbox 
was configured or not.

If this is the desired behaviour the checkbox configuration can be 
removed completely and also the documentation for this feature can be 
updated that this option is not available any more for 4.5.

Kind regards,
Alex
