[TYPO3] Problem with TCAdefaults

[Brian Bendtsen]

Hi

I have made an extension where you can create a record with tt_news 
items as childelement using IRRE. I have created at sysfolder for 
holding these items, but I want all news records to be saved in a folder 
with pid=13

I have inserted this in the pageTS on my sysFolder with the parent records:

TCAdefaults.tt_news.pid = 13

but it has no effect, the news items are still created in the same 
folder at the parent record.

Any hints?
