Compatibility between Robust Foundation API RFA C++ 8.2.2 L1 and E1

Adrian Lulea

Hello,

The last version of my software (Finastra Summit) has been built with RFA 8.2.2 L1.

We just noticed on your website that a kind of emergency version is available: RFA 8.2.2 E1.

We have the following questions:

1. Do you confirm that we should use RFA 8.2.2 E1 instead of RFA 8.2.2 L1 in my next product patch?
2. And is there any compatibility between RFA 8.2.2 L1 and RFA 8.2.2 E1 ?
   • i.e. if we have the product compiled against L1 but at runtime we put E1, will it work?

Kind regards,
Adrian L.

Thank you for reaching out to us.

RFA 8.2.2.E1 contains the fix of the following issue in RFA 8.2.2.L1.

--------
8.2.2.E1
--------
[RFA-882] - CaseId 13627839: The data encoding functions 'DataBuffer::setFromString' and
            'SingleWriteIterator::setEntryFromString' were modified to throw an InvalidUsageException
            instead of encoding default values or zero for the DataBuffer enumerations FloatEnum, DoubleEnum, RealEnum, Real32Enum, Real64Enum, DateEnum and TimeEnum when passed an invalid input that results in an overflow.

You can use 8.2.2.E1 to avoid this issue. Yes, 8.2.2.E1 is compatible with 8.2.2.L1. It is better to rebuild the application with 8.2.2.E1.
