Unable to pipe variables or smart variables into branching logic condition field

[remifrazierucsf]

There are certain significant use cases that would benefit from the ability to pipe variable or smart variables in the "Condition" field.

(For example, a study may desire to double blind instruments between different data collectors such that a baseline survey cannot be seen by data collectors collecting followup surveys.)

@remifrazierucsf, I am confused because we are using Smart Variables in the advanced control field in production:

I'll confess our proposal to deprecate the Advanced Control Field casts some doubt on the long term viability of what I am saying here, but it does work on the current FRSL. I'll take up the Advanced Control Field deprecation in another issue.

Can you share an example of something that fails?

I made the issue about not deprecating Smart Variables at #74
