[TYPO3-english] Is EXT:flux 5.0 incompatible with TYPO3 4.7?

[Roland]

hi everybody,

is EXT:flux 5.0 incompatible with TYPO3 4.7? in the news on 16/12/2012 i 
only read "Flux and FED 5.0 are compatible with 6.0".

I just tryout EXT:fluidcontent which depends on EXT:flux in an 4.7.7 
TYPO3 installation and tried to add one of the twitter bootstrap content 
elements on a page. this results in this error message in the BE:

<quote >
Fatal error: Class 'TYPO3\CMS\Core\Messaging\FlashMessage' not found in 
/var/www/hella/typo3conf/ext/flux/Classes/Service/Configuration.php on 
line 103
</quote>

line 103 says:

<code>
$flashMessage = new \TYPO3\CMS\Core\Messaging\FlashMessage($messageText, 
'Fluid configuration missing', t3lib_FlashMessage::WARNING);
</code>

kind regards

roland
