[Typo3-dev] write page.headerData in userFunc

[Stefan Beylen]

Hello Typolist,

can anyone give me a hint how I can achieve to write headerData in my 
userFunc? If I set it like that

---snip------
$GLOBALS["TSFE"]->tmpl->setup['page.']['headerData.']['788']="TEXT";
$GLOBALS["TSFE"]->tmpl->setup['page.']['headerData.']['788.']['value']="lalala";

print_r($GLOBALS["TSFE"]->tmpl->setup['page.']['headerData.']);
---snap------

i can see it in the print_r - anyways, it doesnt get rendered in the FE :(

anyone has an idea how to solve that?
thx
