[TYPO3-mvc] extjs 4.0 and Extbase+Fluid

[mario chiari]

Hi

I have installed FED 1.3.39.
If I try to open web/page, i get the following error messages:

#1218547409: $hookObject must implement interface
tx_cms_layout_tt_content_drawItemHook

UnexpectedValueException thrown in file
/var/www/html/*****/typo3_src-4.5.2/typo3/sysext/cms/layout/class.tx_cms_layout.php in line 1810.
......

and

t3lib_div::getUserObj
|Class 'Tx_Fed_Backend_MakeQueryArray' was not prepended with 'user_'|


Something I need to fix?
Thanks
mario
