[TYPO3-dev] New Extension does not show anything

[Anja Leichsenring]

Hi Dirk,

I take your code as a example for usage, otherwise I would need to write 
a book now.

First of all, you need a TypoScript Template, what the extension_builder 
should have generated for you. This you need to add to your root 
template, and set at least the PID in setup or constants, where your 
records are stored and looked for.

In your list action, you create a new instance, but you never add it to 
the repository, so no call to the persistence manager will do any good. 
I add the missing line in your code below.

After this, you should see your categories.

Hope this helps.
Kind regards
Anja
