Is anyone familiar with an issue with 2.0

CurrentRecord.Field.isDisabled

not functioning correctly? It looks like field object are lacking the property completely despite the 1.0 to 2.0 map stating that it is the 2.0 version of

nlapiDisableField()

function. I found this thread: https://netsuitehub.com/forums/topic/gap-in-ss-2-0-ability-to-disable-line-level-fields/ but the link does not work and it seems like its suggesting that 1.0 and 2.0 code needs to be mixed.
