[TYPO3-mvc] Persistence/ObjectStorage: Model seems to be unimpressed by modifying its properties

[Hauke Stange]

Moin.

This _isDirty() method returns the 'isModified' property of the
ObjectStorage. I just looked at the $newAllgemeineVoraussetzungen
ObjectStorage object and it has its property 'isModified' set to
'false'.

I can't modify 'isModified' due to its protected visibility.

Could it be that? Then how to set whole ObjectStorages?

Thx for further hints regarding my problem!
