NIO interface issue in 5.4 (default data type handling)

When using the NIO interface, dynamic item references that do NOT include the "@datatype" specifier do not fall back to their default type as they did in earlier releases. The type applied for an item that should default to 'Word' appears to be a 64 bit value instead. This causes significant problems with reading and writing the correct data (user thinks they're reading K1 as a word but are reading as a 64 bit so they are reading/writing to K1-K4…not good).

Channel1.Device1.K1 (this item reference to a SimDemo item would end up using a 64 bit type instead of 16bit)

:::::::::::::::::::::::::::::::::::::::

This issue only affects:

(customers using the 5.4 release) AND (the NIO interface) AND (dynamic item references without the @datatype reference)
