    Default Uncaught TypeError when adding a reference to an existing field in a model

    The following message is displayed in the "unexpected error occurred" dialog when attempting to add a reference linking a foreign key field in the selected model to an existing model (reference property set to use "model" option).

    Uncaught TypeError: model.flyCfg(...).getValueInstance is not a function"

    Both models are already tested and loading data successfully via REST proxy and I'm attempting to add relationships between models. I am new to Sencha products and this is my first time trying to expand on my basic models.

    This is using Architect 4.2.5 with a 6.7 Modern project on Win 7 (64 bit).
