React v15 controlled/uncontrolled

[icodeforlove]

The concept here is extremely elegant.

But it seems like it may be incompatible with react v15, i am getting the following error:

Input elements should not switch from uncontrolled to controlled

When i try to use a field.

[icodeforlove]

The fix for this seems to be the following in all the inputs:

value={value || ''}

The value cant be undefined or null anymore.
