[TYPO3-dev] hooking into Web->List save record

[Markus bertheau]

Hi,

I'm developing an extension with two record types: notes and
categories. Categories are organized as a tree (with a parent_uid in
the categories table). Notes can be in one or more categories. Now
upon every save of a notes record I want to add all child categories
of the selected category to the record. Is that doable in typo3 3.8?

Thanks

Markus
