------------------------------------------

The last issue you raised here https://github.com/kiegroup/drools-wb/pull/1091 was actually due to wrongly written out DMN (I sent you correct one via gchat).
But beside that you explicitly stated that you do not want "partial" solutions

_I don't accept the answer that "top-level collections don't work yet", as they work with some DMNs_

Probably it was not clear enough, but top-level collection *are* broken; even if you see a _green_ status after run is only by chance, and it does not mean it actually made the _right_ comparison you would expect. For example, it turned out that in some cases the DMN engine turned both input and output to _null_, and then the comparison "apparently" succeeded.

Last, making only one single PR at the end was exactly what I meant with:
_This mean that I will close this PR and I will create a new one that will include everything._

> If you have a DMN file with a top level collection like a list of string not as field of a complex object but as top level. The type is not correctly loaded and managed.
> Top-level collection should work also in Rule scenario.
> See dmn-list.dmn as example
