[TYPO3-mvc] Could not determine the child object type - Erst nach Cacheleeren weg

the reflection cache does not respect the no_cache flag nor is it cleared via clear cache button in the BE (TYPO3 4.5). You have to clear it by hand (truncate tx_extbase_cache_reflaction* tables). For development it makes sense to set the reflection life time to a low value via TS (see the extbase_cache_configurator extension - again just for TYPO3 4.5).
