Version 1.9.2.4
Reproduce:
define maxLength 38 for the multiline-attribute "street" and you have two lines e.g. "street" and "street2".
validate_rules = a:2:{s:15:"max_text_length";i:38;s:15:"min_text_length";i:1;}
multiline_count = 2
In the account create an address with
street = some string with 38 chars
and
street2=some string with 38 chars
Then in the checkout select this address and proceed.
=> This leeds to an validation error: "Street cannot have more then 38 chars"
The reason is, that the function validateRule in class Mage_Eav_Model_Attribute_Data_Multiline validates the char-length of both multiline fields anginst the defined 38 maxLength.
FIX:
change:
if (!is_array($value)) {
$value = array($value);
}to:
if (!is_array($value)) {
$value = explode("\n", ($value));
}in magento2 it was fixed already:
