Support detect path via id if property source is set.

[vuongminh-xx]

In version 1.0.4, We can configure an object is not instance of Module when config source property, i suggest in method composeDefaultPath of Item class if source property is set and value isn't an instance of Module, it should be return id value. #L195

[klimov-paul]

Rejected: value path is composed before 'object to be configured' can be determined. Thus there is no way of telling whether it is instance of Module or not.
You should specify item path in array format for standalone configuration setup.
