Fixes #420

fixes #420, still have to make a test for this

[dxlbnl]

Okay, added test, but it's failing for some reason (possibly another bug).

[dxlbnl]

The failing test says:

  1) generate inline helpers component-binding-deep:
     TypeError: Cannot read property 'deep' of undefined
      at renderMainFragment (test\generator\samples\component-binding-deep\main.html:19:26)
      at new Main (test\generator\samples\component-binding-deep\main.html:104:19)
      at env.then.window (test\generator\index.js:109:24)
      at process._tickCallback (internal/process/next_tick.js:109:7)

Which is caused by:

        var widget_initialData = {};
        if ( 'name' in root.root.deep ) widget_initialData.value = root.deep.name;
                data: widget_initialData

I think root.root.deep is wrong, and it should have been root.deep. But I'm not sure.

I think the root. will always be getting prepended already via Generator.js so I believe this can be fixed by just removing the root. that's prepended in addComponentBindings.js. This does make the unit tests pass, but I defer to Rich on whether that's the real solution.

so I believe this can be fixed by just removing the root

spot on — this whole bug was just the result of some careless copying and pasting on my part, I think. Sorry! 😊 Will cut a new release momentarily
