There is a code bug in BxBaseFormView.php
Line: 614
Function: genInputStandard
Bugged code:
$aAttrs['class'] = "form_input_{$aInput['type']}" . (isset($aAttrs['class']) ? (' ' . $aAttrs['class']) : '');
Fixed code:
$aAttrs['class'] = "form_input_{$aInput['type']}" . (isset($aInput['class']) ? (' ' . $aInput['class']) : '');
Not sure if this has been reported or not.
Cheers,
SG
