Glad I'm not the only one... it also can't find:
columns
instances
instance
manageRelatedJoins
updateColumns
updateColumnsJoinView
saveModelOrder
columnOrder
columnsForLabel
setColumnForLabel
updateJoins
joins
add
update
removeWhich is every single method that is called via loadJSONDoc. Something is definitely wrong, I'm glad it wasn't just me.
