Initializing a store with the file backend breaks the gui. For a simple repro, I modified the example notebook quickstart.ipynb so that a store is initialized using a file backend. Changing

enact/examples/quickstart.ipynb

Line 62 in 6187107

"with enact.Store() as store:\n",

to read

with enact.Store(enact.FileBackend('./')) as store:

the example notebook behaves as expected until the gui is created and the invokable is run. Running the invokable through the gui produces

This should be fixed once #29 is in

Store with file backend raises RefError with gui.
