TYPO3 Core

I don't know what exactly makes this happen, but at least it is reproducible:

For some strange reason we needed to order news in a parent / child way. Nothing better than IRRE to do that:

- added two fields to tt_news, one for the "inline" type holding the children and one to hold the uid of the "parent" news

Now here comes the bug:

- Whenever there are children records in my tt_news record, the "keyword" pallete is empty! If "show secondary palettes" is enabled, I don't see the keywords at all (should be directly below bodytext). If I disable that option I get the icon for "secondary palette", but clicking on it gives me an empty palette.

To make it easier to test (go, Oliver, go!), I've made a little extension that just adds that inline fields needed to test this behaviour.

I also had some other "palette" related trouble in the course of our developement with this constelation (parent / child tt_news records), but this "keywords" thing is the only thing I could reproduce. Maybe fixing this fixes all related problems. :)
