Hello!
I pass 3 parameters (let's say: i, n and o) to a page P, that are not null as values coming from data, and as I can see it in the debug console of FF.
I pass these parameters to a sub-component A in the page. If o is not empty (it's a list), everything works fine, but if o is empty, I get the red screen with the "unexpected null value" error!
In the debug console, I can see that the parameters are set for the page P, but null (a, b) or empty (c) for component A.
The console error of FF or Chrome don't tell me which parameter/var is null (see images).
Do you have any idea where this behavior comes from?
