Strange behaviour moving generated arrays and successively generating arrays into nested structure

[TobiasNx]

move_field and copy_field seem to have problems moving generated arrays and generating arrays into nested structures.

Moving

• moving a generated array with a single value is transformed into an simple string-array
• moving a generated array with a multiple values is working

Generating

• generating an array with a multiple values into an nested object is transformed into an array with an object indexing all values as own elements

• generating an array with a single value into an nested object is working

• generating or moving an array into an object of an array is breaking or not working

--- was originally:----
When moving an array in an object of arrays the behavior seems strange.
If you move an array into an object of array the behavior seems okay.

To avoid conflict with #102, should be started after the planned first PR for #102.

Some behaviour seems to be solved.
