[TYPO3-mvc] show first datasets with small domain model

[Domi]

Hello,

here comes a very beginner question: with the extbase_kickstarter I 
created a very simple DomainModel and just want to play around but I 
dont get my through the backend created data showed.

I set up a storagePid and everyelse is created by extension_builder. But 
in the table nothing shows up, only the table header and a link for 
creating a new dataset. But if I fill this form out, the table stays 
empty. What do I miss?

Thanks for any startup help

Dominic
