Hi,
What can be done is editing the view "user / editaddress" (backend template) and relplace the line:
echo $this->fieldsClass->display($oneExtraField,$this->address->$fieldName,'data[address]['.$fieldName.']',false,''.$onWhat.'="hikashopToggleFields(this.value,\''.$fieldName.'\',\'address\',0);"'); ?>
By:
echo $this->fieldsClass->display($oneExtraField,$this->address->$fieldName,'data[address]['.$fieldName.']',false,'backend'.$onWhat.'="hikashopToggleFields(this.value,\''.$fieldName.'\',\'address\',0);"'); ?>
And in the class field.php (administrator/components/com_hikashop/classes/field.php) replace the line:
$size .= empty($field->field_options['readonly']) ? '' : ' readonly="readonly"';
By:
if(!preg_match('/^backend/',$options))
$size .= empty($field->field_options['readonly']) ? '' : ' readonly="readonly"';
$options = preg_replace('/^backend/','',$options);
