[TYPO3-mvc] Generating RSS Feed with ExtBase / Exception from Repository

[Michael Knoll]

Hm - seems like I found my error myself... I missed the following line 
within my persistence - section of TS config:

storagePid = {$plugin.tx_blogexample.persistence.storagePid}

After setting this to the right PID, everything works...

I still ask myself, why this does not happen, if I'm using it as a page 
content - perhaps there is a bug in the repository-code? As I 
implemented a function that takes a PID as an argument and queries the 
records for a given PID...

But ok - for me it works at the moment...

Greetings!

Michael
