[TYPO3-mvc] itemArrayProcFunc with Extbase

[Lars Peipmann [Infield Design]]

Hi there,

I try to use itemArrayProcFunc in TMENU with Extbase. Unfortunately I 
get this Message:

Fatal error: Class 
'Tx_IdCoastandards_Domain_Repository_ProgramRepository' not found in 
/home/coadev/public_html/typo3_src-4.5.4/t3lib/class.t3lib_div.php on 
line 5308

I did all like in this post:
http://lists.typo3.org/pipermail/typo3-project-typo3v4mvc/2009-June/000487.html

can you help me with that?

Thanks,
Lars
