Using array slice in tuple causes evaluation error

[CervEdin]

Using array slice in tuple seems problematic

tuple( array[int] of int ): works = ( [ [1, 2, 3][i] | i in 2..3 ], );
tuple( array[int] of int ): fails = ( [1, 2, 3][2..], );

output outputJSONParameters(); % empty?

Error: evaluation error: arrays of arrays not supported

seen in 2.8.7 and 2.8.8, build 1519497721

unrelated but also the outputJSONParameters seems empty when I print it 🤔

Yes, that seems like a bug.

outputJSONParameters only outputs parameters without right-hand sides in the model, so you'd have to do something like

tuple( array[int] of int ): works; % No RHS
works = ( [ [1, 2, 3][i] | i in 2..3 ], ); % Separate assignment (or from dzn)
output outputJSONParameters();
