I have created a series of integer fields with minimum value 0, maximum 100. Unfortunately, zero is not accepted at registration - the error is "Fieldname: This input value is not authorized."

I've searched every post I could find about this issue but have only found that leading zeros are stripped - which makes sense - but are perhaps single zeros being stripped as well?

I know it should be possible to write a text field regex that would accomplish somewhat the same thing, but I'd prefer to use the integer field if at all possible.

After some more digging, I think the problem is in this line of code within class CBfield_integer in plug_cbcore:

[code:1]if ( in_array( (int)$value, $forbiddenContent ) ) {
$this->_setValidationError( $field, $user, $reason, _UE_INPUT_VALUE_NOT_ALLOWED );
$validated = false;
}
[/code:1]

Removing (int) from that first line resolves the issue:

[code:1]if ( in_array( $value, $forbiddenContent ) ) { [/code:1]

Yes, indeed that works just fine.
