Using Global get Ex on Noop call giving error when deploying app

Hi jjEvans,

This trips up a lot of folks. It has to do with the AppGlobalGetEx returning a MaybeValue which needs to be included in a Seq (or some other expression) prior to calling hasValue

You may try something like

   myStatus = App.globalGetEx(0, Bytes("Count"))
   handle_noop = Seq(
    myStatus,
    Cond(
       [And(
            Global.group_size() == Int(1),
            Txn.application_args[0] == Bytes("Add"),
            myStatus.hasValue()
        ),add],
        [And(
            Global.group_size() == Int(1),
            Txn.application_args[0] == Bytes("Deduct"),
        ), deduct]
   )
)

This is a strange way to offer this functionality so I hope will be tweaked in upcoming versions of PyTEAL.
