[TYPO3-dev] Some Extbase Controllers are not cached

[roberto blanko]

Hello,

my problem is, that the output of some controllers within a plugin is not
being cached. Or in other words: it is being cached (a record in the
page_cache table is being created) - but the cache is being newly generated
at every page call.

I didn't disabale caching for controllers in ext_localconf using
Tx_Extbase_Utility_Extension::configurePlugin() an there are no uncached
_INT elements an the page. What could be the cause for that? I want all my
Extbase output cached until someone clears the cache manually.

Help is very appreciated.
