Add Element.setProperty(String, List<SomeSupportedType>)

[Artur-]

There should be a setProperty method which takes a list of primitives or other supported types such as beans (see #7307)

getElement().setProperty("persons", myPersons);

should set a persons property as an array to the given persons.

[Legioth]

The same questions as in #7307 (comment) also apply here, but it probably makes sense to keep all the discussion in a single issue.
