That would work, if the modifier AEs that create new views are not cascaded.

I added a simple AAE created for investigating the problem at the end.

Maybe I did something wrong, but I tested different variants and
debugged the UIMA implementation.

There are five AEs:
- CWEngine: a simple Ruta script (input=input of AAE)
- ModifierCW: Ruta modifier that creates a new view (input=input of AAE,
output=norm_1_out)
- SWEngine: a simple Ruta script (input=norm_1_out)
- ModifierSW: Ruta modifier that creates a new view (input=norm_1_out,
output=norm_2_out)
- SimpleEngine: a simple Ruta script (input=norm_2_out)

ModifierCW works since it uses the default view, but ModifierSW fails
because it gets also the default view despite the mapping.
