Required Checkbox images dont validate

About the new search feature of v1.5.6 read here:

About v1.5.6 checkbox field and select field, neither of them has a bug:
-- the select field is not validating when it has value zero (in all FC versions), because our validation process will not accept it as a valid value, maybe you could not call this a bug, since usually zero and empty are considered invalid, i will check if we can change this, i don't want to break existing behavior.
-- about the checkbox image not validating when having more than one value i cannot reproduce this, maybe it is because of you have some javascript code that is also loaded along with the FLEXIcontent code.

Only line changed in v1.5.6 is this line in file plugins/flexicontent_fields/chechboximage.php:
$required = $required ? ' required validate-checkbox' : '';

change it to what it was in v1.5.4:
$required = $required ? ' required ' : '';

and test ...
