I have defined:
app.select_solver_calc_properties.Items = {'Fminsearch', 'Fmincon', 'Look-up Table', 'Genetic Algorithm'};
app.select_solver_calc_properties.ItemsData = {'[1 2 3 4]'};
When I run
app.select_solver_calc_properties.Value = 3;
I get the error:
'Value' must be an element defined in the 'ItemsData' property.
I've consulted the dropdown page with no success. What am I doing wrong?
EDIT: The issue is that the inspector defaults to a non-numeric type for ItemsData. I'm not sure how to fix this since I can't edit the component setup part in App Designer.

You are using char array to set the UserData property. You should just pass it a numeric array
app.select_solver_calc_properties.ItemsData = [1 2 3 4];

For a large application this is going to make the startup quite bulky, but I suppose it's the best solution. Hopefully this gets fixed in a future release. Thanks.

I am glad to be of help.
Hopefully, they will make it possible to specify a numeric array directly from the inspector panel.
