renderField for fieldset fields does not render anything

[LAPS]

Can you confirm that the function renderField for fieldset fields, even having the file /site/templates/fields/fieldName.php or /site/templates/fields/fieldName/$file.php (using $file argument), does not render anything as expected?

$page->renderField('fieldsetName')
// returns nothing

... or am I wrong on something?

To make the renderField function to work for fieldset fields you must specify a $value to render that is not null.

For example, using the /site/templates/fields/fieldName/$file.php (using $file argument):

$page->renderField('fieldsetName', $file, $value)
$page->renderField('fieldsetName', $file, '')
