[TYPO3-mvc] Possible misunderstanding of repository / variable scope?

AFAIR, it executes the query and then checks the result. But i have not
had a look at this part for quite some time. The query also depends on
default query settings or the configured storage page. So two plugins
from the same type can get different results for a findAll query.

Good question, i don't know. Perfect time to start your debugger ;)

Indeed :)
