Sweep2 Input Problem... about Referenced Curve(Line) in build 0.7

Hello.

I want to use Sweep1 or 2 component making variable surfaces with flexible section.

In build 0.6, that component accepts any curve (recreated in grasshopper) for input data. But

in build 0.7, it allows only 'Referenced Curve', selected directly from Rhino Viewport.

Is there any possible solution?
