[TYPO3-dev] additionalHeaderData in extensions, can't get correct order when caching is enabled

[Cyrill Helg]

Hello

I'm writing on an extension that depends on a library extension. In the lib 
ext, the js is added with $GLOBALS['TSFE']->additionalHeaderData['foo']. I do 
that as well in my ext, but the code from ext is before the library so it 
fails...

How can I control that order? The strange thing is that the lib extension 
is "loaded" after my extension, although in the ext list its after the lib 
ext, or what actually controls the order of the loaded extensions?

The thing is that if I disable caching of the plugin, it works as expected, 
but I can't succeed with caching enabled.

Thanks for any help.
