AttributeError : 'Data' object has no attribute when accessing custom data in onData

hi,

When trying to access any custom data in onData, populated in the Reader method of the  overloaded PythonData class , I get this error 'Data' object has no attribute when accessing  x.

As a demo to the issue, in the attached sample BubbleAlgorithm backtest, I am able to access data["CAPE"].Cape , but not able to access data["CAPE"].RealEarnings. 

Update Backtest

You can un-comment line 127 , to replicate my issue.

I received the following reply from Alex from QC

"Please use data["CAPE"].Realearnings. The implementation of dynamic attributes doesn't support camelCase."

That solves my issue.
