[TYPO3-mvc] Object Accessors & lazy object loading

[Frank Mey - NEW.EGO]

Hi,

Franz - problem is solved, my thinking and your comments are right :).
We migrated old data-basis of an IIS/ASP Installation to the extbase/fluid
tables.
The data of uid_local and uid_foreign was switched by the migration script
-> programmers error (not mine luckily ;)  ),
so the extension couldn't find any heftbereiche :). I switched it back and
all works fine,

thx for clarification of the topic and lazy loading anyway !
Greetz from munich,
frank
