[TYPO3-english] Extbase: Introduce explicit saving of modified domain objects

[Vitoandre D'Oria]

Hey folks!

We are still locked to Extbase 1.3 but will switch to 6.2 next year

Thus i was reading the Extbase Breaking Changes and stumbled over the following:
http://forge.typo3.org/projects/typo3v4-mvc/wiki/Breaking_Changes#From-Extbase-60-to-Extbase-61

"Introduce explicit saving of modified domain objects"

The related Ticket: http://forge.typo3.org/issues/47251

Im wondering if i really would need to update all models as described ??

While it makes sense (i neither like the current behaviour) i am wondering if this also applies on nested models???
What happens if i got such a structure:

parent -> child -> grandChild

Would it be enough to update the parent in order to create/update the child and grandChild?

Othewise it sounds ugly to traverse the whole tree to update each model

If the second? How are you doing this? Is there some extbase magic to do this? or do we just have to foreach ... bleh!

Also does this only apply on "update" or "create" too?

Hope someone can shed some light as the ticket nor breaking changes explain it well enough
