When trying to implement [Tag Max Value no SQL - #2 by pturmel](https://forum.inductiveautomation.com/t/tag-max-value-no-sql/35649/2) I found that using key access with brackets i.e. `state['max']` results in an `Error_ExpressionEval`. Fortunately, using `state.get('max')`. still works correctly.

EDIT: I'm guessing it's because it throws a `KeyError`, d'oh! I was thinking that maybe I could "pre-load" the key but I also bet that it resets the "state" dictionary whenever the expression is edited.
