Poll feature: Can't create new poll document (and use it)

Note:

Using archetype 1.02.10-SNAPSHOT and 1.03.00-SNAPSHOT
Note that archetype 1.02.10-SNAPSHOT defines Essentials 1.02.08 and not the latest snapshot

1) Create project with essentials archetype and add poll feature
2) Go to content/.../polls/ and add new poll item
3) Add name and click OK.
Expected: Poll document open in document editor area
Actual:
Exception:
