[TYPO3-dev] FAL in an Extbase 6.0 extension... but how?!

[Henjo Hoeksma | Stylence]

Hi Anders,

I am more than eager to see an example / bestpractice solution for this as
well. I have found there's some basic implementation in Extbase atm.  See
the functional test and the domain models that are there.

Some insights, or a small docu on how the architecture of FAL is setup
would be great.

Kind regards,

Henjo

Problems are small because we learned how to deal with them.
Problems are big because we need to learn how to deal with them.
